Question
A ball of mass 0.6kg, initially at rest, is kicked directly toward a fence a point 20m away. The velocity of the ball as it leaves the kicker's foot is 17 m/s at angle of 50 degrees above the horizontal. The top of the fence is 7m high. The kicker's foot is in contact with the ball for 0.05s. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s^2. 1) Hint: Consider the diameter of the ball to be negligible. How far above the top of fence will the ball pass? Answer in units of m 2) What is the vertical component of the velocity when the ball reaches the plane of the fence? Answer in units of m/sSubscribe our channel for more SOLUTION
