Solve the all parts of following problem:
Problem: An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. But she does have devices to measure distance and time accurately. She knows her own mass is 75.9kg, but she is unsure of the mass of a large gas canister in the airless rocket. When this canister is approaching her at 3.40m/s , she pushes against it, which slows it down to 1.30m/s (but does not reverse it) and gives her a speed of 2.10m/s .
Part A: What is the mass of this canister?
Part B: How much kinetic energy is "lost" in this collision?
I need help to find how much kinetic energy is "lost" in this collision.
A rock is tossed straight up with a velocity of 16m/s When it returns, it falls into a hole 10m deep. What is the rock's velocity as it hits the bottom of the hole
A photographer in a helicopter ascending vertically at a constant rate of 15.0m/s accidentally drops a camera out the window when the helicopter is 60.0m above the ground. How long will the camera take to reach the ground
