A small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 6.60 m to the bottom of the incline is 3.80 m/s. Q: What is the speed of the block when it is 3.80 m from the top of the incline?

A golf ball is dropped from rest from a height of 9.90 m. It hits the pavement, then bounces back up, rising just 6.30 m before falling back down again. A boy then catches the ball when it is 1.40 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch. Number i Units

Kalea throws a baseball directly upward at time t = 0 at an initial speed of 14.5 m/s. How high h does the ball rise above its release point? Ignore air resistance and use g = 9.80 m/s². h = m

-b+√b²-4ac 2a x = xo + vot + ½ât², v = vô + āt, v² = v² + 2ảAx, t = ² Problem 1: A ball is thrown straight up from the ground. The ball reaches a maximum height of 5 m. For simplicity, use g = 10 m/sec². a) What is the initial speed of the ball? Answer: 10 m/sec b) What is the time it takes the ball to reach the maximum height of 5 m? Answer: 1 sec c) What is the time it takes the ball to hit the ground? Answer: 2 sec d) At what times is the ball at a height of 3 m above the ground? Answer: 0.37 sec and 1.63 sec e) What is the velocity of the ball when it is at a height of 3 m above the ground? Answer: +6.3 m/sec or -6.3 m/sec.
