A straight slide, of length of exactly 3.80 m long, is inclines at 44.0°. You give a child a careful push, she slides down and at the bottom is moving at 13.4 m/s. Assuming the slide is completely frictionless, how fast is the child moving right after you pushed her? 11.3 m/s 11.9 m/s O 10.3 m/s O 6.21 m/s

Question 2
A baseball player standing on the ground throws a ball straight up. The ball leaves the player's hand with a speed of 3.48 m/s and is in the air for 1.60 s
before hitting the ground. How high above the ground was the baseball player's hand when he released the ball?
O 12.5m
6.98 m
18.1 m
5.57 m
Question 3
A small child is climbing up a slide angled at 15.0° above the horizontal. They only make it 0.900 m up the slide before they give up, stop, and then slide
back down. When the child reaches the bottom of the slide how fast will they be going?
214 m/s
04.13 m/s
4.20 m/s
0.553 m/s
