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 is0.85m and the acceleration achieved during the time the jumper is extending their legs is1.2times the acceleration due to gravity g .d=0.85ma=1.2timesHow far can they jump in meters? Assume the person leaves at an angle of 45 and on level ground.2)An express train passes through a station. It enters with an initial velocity of20.5m/s and decelerates at a rate of0.14m/s2as it goes through. The station is202m long.v=20.5m/sa=0.14m/s2l=202ml1=122m>Part (c)If the train is122m long when does the end of the train leave the station?>Part (d)What is the velocity of the end of the train as it leaves in m/s?3)d=21.5mFind the initial speed of the ball if it just passes over the goal 2.4 m above the ground given the intitial direction to be 40 above the horizontal.
