A truck with a mass of 1600 kg and moving with a speed of 13.5 m/s rear-ends a 585 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. V car 6.27 m/s V truck = 19.77 X m/s
3. Bob and Linda are sweethearts that enjoy skating arm in arm. Bob has a mass of 85 kg and Linda has a mass of 60 kg. Initially they are skating together with a speed of 3.0 m/s. Then Bob whispers a dirty joke into Linda's ear, causing her to push him in the oppposite direction of their motion. If Bob's final speed is 1.0 m/s, what is Linda's final speed?

ASAP PLS SHOW ALL WORK In the movie “The Martian”, an astronaut needs to propel himself through space to get to a spaceship. He attempts to do this by puncturing the glove in his spacesuit, which contains 3.00 kg of air under pressure. He is initially at rest, with a mass (including the spacesuit and air) of 75.0 kg. If the air comes out at 28.0 m/s at a constant rate, what final speed does he reach when the air is used up?

A 5 kg cart, cart A, moves with v=3m/s and collides with another 5 kg cart, cart B, head on at rest. Neglecting air resistance and friction, do the following: Find the final velocity of the carts if the collision is perfectly inelastic. Find the linear momentum of each car before and after the collision if it is a perfectly inelastic collision. Find the kinetic energy before and after the collision if is perfectly inelastic. If the collision were elastic, what would be their final velocities? What would be the kinetic energy of each before and after the collision?
You’ve probably seen cartoons in which a person is blown backward by a sneeze. Could this actually happen? Suppose a 80 kg woman sneezes rather violently while standing motionless on a frictionless surface, ejecting 3.0 g of air and water vapor at a speed of 40 m/s . These are typical values for a sneeze. - If the air is ejected horizontally, how fast is the woman moving after the sneeze?
1. A cosmonaut (total mass is 150 kg, including himself, his space suit, oxygen tanks, and a toolbox) accidentally floats away from the Mir space station at 0.667m/s without a tether. What minimum speed and in what direction does he need to throw his 10 kg toolbox in order to stop floating away from Mir? Please make sure you draw a clear diagram, identify initial and final states of the system, draw a bar chart consistent with the situation, and explain your reasoning.
