In the world athletic championships held in Tokyo, Japan in 1991, Mike Powell set the world record for the men's LONG JUMP at 8.95 m. If Mike's hang time was 0.92 s, a) What was the initial horizontal component of his velocity when he jumped?(Round your to the nearest tenth) b) What is the vertical component of his jump? (Round your to the nearest tenth). c) Use your answers for parts a) and b) to determine Mike's initial velocity and direction of his jump. If Mike weighed 170 lbs, d) what is his mass in kg? e) Using the vertical component of speed, determine the KE in the vertical direction. f) Use the law of conservation of energy to determine the maximum vertical height of the jump. g) What is the minimum amount of work (in Joules) that Mike must exert in pushing off the ground?
