Homework Answers
2 a) potential energy = kinetic energy
mgh = 0.5mv^2
v = sqrt(2gh)
= sqrt(2*9.8*0.6)
= 3.43 m/s
so the initial speed is 3.43 m/s
c) according to Newton's third law ,
reaction from ground = Jumper's weight

A basketball player is running at 4.70 m/s directly toward th basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. a) what vertical velocity does he need to rise 0.0700 above the floor? b) How far from the basket must he start his jump to reach his maximum height at the same time he reaches the basket?

In basketball, hang is an illusion in which a player seems to weaken the gravitational acceleration while in midair. The illusion depends much on a skilled player's ability to rapidly shift the ball between hands during the flight, but it might also be supported by the longer horizontal distance the player travels in the upper part of the jump than in the lower part. If a player jumps with an initial speed of Vo = 6.00 m/s at an angle...

A basketball player is running at 4.3 m/s toward the basket when he jumps into the air to dunk the ball. he maintains the same horizontal velocity while in the air. What vertical velocity does he need to rise 0.750 m above the floor in m/s? And at what horizontal distance from the basket, in meters, must he start his jump to reach his maximum height at the same time as he reaches the basket in m?

A 1.85 m tall basketball player attempts a goal 14.03m from the basketball hoop, which is at the height of 3.05 m. The acceleration of gravity id 9.81 m/s^2. If he shoots the ball at an angle of 46.0 degree, at what initial speed must he throw the basketball so that it goes through the hoop without striking the board? What is the time required for the ball to reach its maximum height? Determine the maximum height reached by the...

A 75-kg volleyball player performs a maximum-effort vertical jump with an initial velocity of 3 m/s. The player leaves the ground with an upright body position and also touches down with the same body position. Answer the following: ua A. How much will the player's center of mass (COM) travel in the air along the vertical direction during the ascending phase of the jump? Compute the maximum kinetic energy of the player during the jump. C. Compute the maximum potential...

2. Excellent human jumpers can leap straight up to a height of 120 cm off the ground. To reach this height, with what speed would a person need to leave the ground? Express your answer to two significant figures and include the appropriate units. 3. A basketball player can jump to a height of 1.1 m off the ground, so he can easily dunk a basketball. For such a leap, what is his "hang time" - the time spent in...

Please answer all questions. 1. One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.4 m/s in 2.34 s , what will be his total time? 2. Excellent human jumpers can leap straight up to a height of 120 cm off the ground. To reach this height, with what...
