Help with the following question
A ball of mass 0.3 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker’s foot is 17 m/s at angle of 47 ◦ above the horizontal. The top of the fence is 6 m high. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s2 (meters/seconds/squared). 1) How far above the top of fence will the ball pass? Consider the diameter of the ball to be negligible. 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/s.
Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.41 m, and observe that it hits the floor 0.421 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 1 43.5 m/s^2 2 43.5 m/s^2 3 13.6 m/s^2 4 20.4 m/s^2
