A basketball is thrown horizontally with an initial speed of 4.90 . A straight line drawn from the release point to the landing point makes an angle of 30.0 with the horizontal. What was the release
Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. When the balls collide, they are moving in opposite directions,
What is the longest "hole in one" that the golfer can make, if the ball does not roll when it hits the green?
The click beetle can project itself vertically with an acceleration of about 400g (an order of magnitude more than a human could survive!). The beetle jumps by "unfolding" its 0.57-cm long legs (a)
A 4 kg block and a 2 kg block can move on the horizontal frictionless surface. The blocks are accelerated by a +12N force that pushes the larger block against the smaller one. Determine the force th
