Two stunt men are going to jump out of a stationary balloon 457 meters off the ground, jumper A will jump first, pulling his parachute at 4 seconds after the jump. Jumper B will jump precisely 20 seconds after jumper A. Jumper B is slightly heavier than jumper A, when their chutes are open, jumper A falls at 3.0 m/s while jumper B falls at 3.2m/s. After how many seconds will jumper B requires to pull his parachute after leaving the balloon to land at precisely the same time as jumper A on the ground? How long does the entire stunt take from the instant jumper A leaves the balloon?
A 23.7 g bullet is shot into a 4706 g wooden block standing on a frictionless surface. The block, with the bullet in it, acquires a velocity of 0.982 m/s. Calculate the velocity of the bullet before striking the block. Amswer in units of m/s.
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 25.00 m/s. The vehicle then slows at a constant rate of 1.1 m/s2 until it stops. (1) How much time elapses from start to stop? ..
