A projectile is launched with an initial velocity of 40 m/s at 60° above the horizontal. Neglecting air resistance, what is horizontal component of the projectile's acceleration?
EXPLORE A projectile is launched with a launch angle of 30° with respect to the horizontal direction and with an initial speed of 40 m/s. (A) How do the vertical and horizontal components of the projectile's velocity vary with time? (B) How long does it remain in flight? (C) For a given launch speed, what launch angle produces the longest time of flight? CONCEPTUALIZE Consider the projectile to be a point mass that starts with an initial velocity, upward and...

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 cannon fires a projectile with an initial velocity of 300 m/s at 61.0° above the horizontal. The projectile impacts a hillside 40.0 s after firing. Let the +x-direction be directly ahead of the cannon and the +y-direction be upward. Find the x- and y-coordinates of the projectile's impact point, relative to its firing point (in m). x= m y= m
air resistance, the projectile will travel what e muzzle velocity is 980 m/s. Neglecting A large cannon is fired from ground level at an angle of 30° above the horizontal. The muzzle velocity is 980 m/s. Neglecting horizontal distance before striking the ground? O 8500 m O 4300 m O 43,000 m O 170,000 m O 84,000 m
A projectile is launched with an initial speed of 51.0 m/s at an angle of 31.0° above the horizontal. The projectile lands on a hillside 3.65 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) (a) What is the projectile's velocity at the highest point of its trajectory? magnitude direction (b) What is the straight-line distance from where the projectile was launched to where it hits its target?
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...
A projectile is launched with an initial speed of 41.0 m/s at an angle of 33.0° above the horizontal. The projectile lands on a hillside 3.75 s later. Neglect air friction.
