A solid sphere starts from rest and rolls without slipping a distance of 8 m down a roof that is inclined at 25˚. The roof’s edge is 5 m high from the ground. How far horizontally from the roof’s edge does the sphere hit the ground?
A ball is thrown from ground level vertically upwards with an initial velocity of vi. Draw a velocity-time graph of the ball’s motion. Consider collisions with the ground are absolutely elastic and neglect air resistance.
A bomber flies with a constant velocity of 50 m/s horizontally and wants to hit a target traveling 20 m/s (same direction) on a highway 1000 m below. What is the horizontal distance of the bomber from the target so that a bomb released from it will hit the target?
One stone is thrown upwards from a point on the ground with an initial velocity v1 and simultaneously another stone is dropped from a height. They reach the ground at the same instant. Compare the velocities which they have attained.
An airline passenger drops a coin while the plane is moving horizontally at 240 m/s. What is the velocity of the coin relative to the plane and relative to the Earth when it strikes the floor 1 m below its point of release?
What is the minimum velocity Vo with which an object must be thrown at an angle of α = 60° to the horizontal, so that it flew over a wall height of h = 6 m, if the wall is at the distance of d = 5 m from a point of throwing?
