A smooth spherical object (the first object) is projected
horizontally from a point a vertical height
H = 25.02 metres above horizontal ground with a launch
speed u = 22.06 ms-1.
A second identical object is projected from ground level with
launch speed v and at an angle θ above the
horizontal. Calculate the value of this launch
angle θ in radians, if the second object
is to have the same horizontal range and the same time of flight as
the first object. Give your answer to 3 decimal places and take
g = 9.81 ms-2.

1. A projectile is launched horizontally from a height above level ground of 3 m. When it hits the ground, it's horizonta displacement from the launch point is 7 m. a. b. How much time does it spend in flight? With what speed was it launched? Suppose the projectile were now launched from the same point at an angle of 45 above the horizontal. a. b. How much time does it spend in the air? What is its horizontal displacement...
On Planet A you fire a projectile horizontally from the edge of a vertical cliff 65.2 m above the ground, with an initial speed of 76.4 m/s. The projectile lands 43.8 m away from the base of the cliff-- What is the value of g for Planet A? On Planet B you fire a projectile from the ground at an initial speed of 61.2 m/s at an angle of 45.5 degrees above the horizontal. The projectile lands 31.3 m away...
Three balls are projected at the same speed from a cliff. Ball 1 is fired horizontally and hits the ground at t1. Ball 2 is fired at an angle of 30 degrees above the horizontal plane and hits the ground at t2. Ball 3 is fired at an angle of 60 degrees above the horizontal plane and hits the ground at t3. Which ball hit the ground from least to greatest. Which equation would you use to calculate the distance...
3.00 s after being projected from ground level, a projectile is displaced 27.0 m horizontally, and 45.0 m vertically above its launch point. a) what was the initial horizontal component of the velocity? b) What was the initial vertical component of the velocity? c) what was the initial velocity of the projectile in polar notation?
A small, spring-loaded cannon launches a golf ball from level ground with an initial speed vi at an angle θi with the horizontal. The golf ball lands a horizontal distance R from its launch point. The highest point the golf ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the golf ball is in motion t =...
Two identical objects start at the same height above level ground. Simultaneously, object A is dropped and object B is launched horizontally with a speed of 20 m/s. Assume that air resistance is negligible. a) Which object hits the ground first, or do they hit the ground at the same time? b) Which object hits the ground with the greatest speed, or do they hit the ground with the same speed? c) If the two objects started at a height...
1. 2. Numerical Problems An aeroplane is flying horizontally at a speed of 100 m's releases a bomb at a height of 500 m. Find (1) the time taken by the to reach the ground. (ii) The horizontal distance where the bomb strikes the ground A bomb is dropped from an aeroplane when it is directly above a target at a height of 1500 m. If the speed of the aeroplane in the horizontal direction is be 540 km/h, calculate...
D) Both B and C Two balls A another in the same vertical plane. After 1 sec from launch, ball A hits a horizontal fixed plank on completely inelastically, moves for 1 sec on the smooth surface of the plank and falls to ground at A', in a further 1 sec. Ball B hits the plank eleastically and falls to ground at 9. and B are projected horizontally with same velocity from the top of a building one A'B 5(2-1)metre,...
If an object is thrown with a velocity of v feet per second at an angle of θ with the horizontal, then its flight can be modeled by, x = (v cos θ ) t and y = v (sin θ ) t - 16 t2 + h where t is in seconds and h is the object's initial height in feet above the ground. x is the horizontal position and y is the vertical position, and - 16 t2...
A metal marble is launched with a speed of v0 = 30.0m/s at 5.0 ◦ relative to the horizontal, from a height of 1.0 m above ground, and towards a very tall vertical wall, which is 6.0 m away from the launch position. The projectile may first hit the wall, or the ground. Whichever it turns out to be, assume that this is an elastic, specular collision, so that the projectile bounces off. After some time, the projectile will have...
