Two athletes jump straight up. Upon leaving the ground, Adam has half the initial speed of Bob. Compared to Adam, Bob jumps a) 0.50 times as high. b) 1.41 times as high. c) twice as high. d) three times as high. e) four times as high.

Step 1
This is because the kinetic energy (1/2 mv^2, where m is mass and v is initial speed) is converted into potential energy (mgh, where m is mass, g is gravity, and h is height) at the peak of the jump. Show more…

Two athletes jump straight up. Upon leaving the ground, Adam has half the initial speed of Bob. Compared to Adam, Bob is in the air a) 0.50 times as long. b) 1.41 times as long. c) twice as long. d) three times as long. e) four times as long.
A red ball and a green ball are simultaneously thrown horizontally from the same height. The red ball has an initial speed of 40 meters per second, and the green ball has an initial speed of 20 meters per second. Compared to the time it takes the red ball to reach the ground, the time it takes the green ball to reach the ground will be: [a] the same [b] twice as much [c] half as much [d] four times as much

Two children are playing on two trampolines. The first child bounces up one-and-a-half times higher than the second child. The initial speed up of the second child is 4.0 m/s. ($a$) Find the maximum height the second child reaches. ($b$) What is the initial speed of the first child? ($c$) How long was the first child in the air?
