A ball is thrown 45" to the ball's path. What is the velocity of the ball,...
2. A baseball thrown from the outfield, a golf ball, or a thrown football, all will follow a trajectory (path) that has horizontal as well as vertical displacement components. If we neglect the air friction on the ball, the path will be a perfect parabolic trajectory. The equations for the displacement of the ball are: Take gravity g as 9.81 meters per second, and the initial velocity, Vo, equal to 35 meters/second. Use Excel to show the ball trajectory for...
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 ball is thrown with an initial velocity, V, of 160 ft./sec, directed at an angle, 0, of 53° with the ground. (a) Find the x and y components of vo. (b) Find the position of the ball and the magnitude and direction of its velocity when t = 2 seconds. (c) At the highest point of the ball's path, what is the ball's altitude h, and how much time has elapsed? (d) What is the ball's range d? (see...
A ball is thrown with a velocity of 40 m/s at an angle 45 degree with the ground. Calculate the maximum height which the ball can reach. Assume that the acceleration due to gravity, g=10 m/s on the surface of the earth
At the edge of a roof a ball is thrown at 12 m/s at +45 degrees. The second ball is thrown from the same location at 12 m/s at -45 degrees. Both balls strike the ground at the same time. The first ball is thrown at to, a second ball is thrown at t1, and the building is 100 m tall. a) What is the velocity of the first ball when it strikes the ground? b) What is the velocity...
The magnitude of a velocity vector is called speed. Suppose that a wind is blowing from the direction N45°W at a speed of 50 km/h. (This means that the direction from which the wind blows is 45° west of the northerly direction.) A pilot is steering a plane in the direction N60°E at an airspeed (speed in still air) of 100 km/h. The true course, or track, of the plane is the direction of the resultant of the velocity vectors...
PROBLEM: A ball is thrown downward from the top of a building at an angle of 30.0° below the horizontal. The point of release is 49.0 m above the ground and the ball lands 67.7 m from the base of the building. (a) How long does it take for the ball to hit the ground? (b) Find the ball's initial speed. (c) the speed and angle of the velocity vector with respect to the horizontal at impact. Neglect air resistance.
1. A ball is thrown with an initial velocity of 25.0 m/s in a direction that makes a 32.0° angle with the horizontal (Assume it was thrown from ground level). a. What is the maximum height of the ball relative to the ground? b. What is the velocity (magnitude and direction) of the ball att-0,708 s
A ball is thrown off the top of a 300m tall building with a velocity of 50m/s at an angle of 20 degrees below the horizontal. How far does the ball travel horizontally before hitting the ground?
8. A ball is thrown horizontally from a roof at 12.0 m/s. find the ball's velocity 2 s later. 9. A ball is thrown 40° above the horizontal at 4.0 m/s. Find the horizontal and vertical components of its velocity after 0.50 s. 10. A ball is thrown 28° below the horizontal at 4.0 m/s. Find the horizontal and vertical components of its velocity after 0.78 s.
