1) In the standing broad jump, one squats and then pushes off with the legs to see how far one can jump. Suppose the extension of the legs from the crouch position is 0.85 m and the acceleration achieved during the time the jumper is extending their legs is 1.2 times the acceleration due to gravity, g .
d = 0.85 m
a = 1.2 times
An express train passes through a station. It enters with an initial velocity of 20.5 m/s and decelerates at a rate of 0.14 m/s2 as it goes through. The station is 202 m long.
v = 20.5 m/s
a = 0.14 m/s2
l = 202 m
l1 = 122 m
How long is the nose of the train in the station in seconds?Part (b) How fast is it going when the nose leaves the station in m/s?
Suppose a soccer player kicks the ball from a distance 21.5 m toward the goal.
d = 21.5 m
