Two friends, Al and Jo, have a combined mass of 168 kg. At an ice skating rink they stand close together on skates, at restand facing each other, with a compressed spring between them. The spring is kept from pushing them apart because theyare holding each other. When they release their arms, Al moves off in one direction at a speed of 0.72 m/s, while Jo movesoff in the opposite direction at a speed of 1.4 m/s. Assuming that friction is negligible, find Al's mass.kgAdditional MaterialseBook3,9208? ? TOMacBook Air%2324Vo3T

Beatrice stands at rest on her skateboard. The mass of Beatrice and the skateboard together is 75 kg. Isaac Newton throws a 3.0 kg ball horizontally to the right at 4.0 m/s to Beatrice, who catches it. (a) What is the final speed of Beatrice and the skateboard? (b) How much mechanical energy was lost in the process?
Two blocks with masses m1 = 1.4kg and m2 = 4.6kg are at rest on a frictionless surface with a compressed spring between them. When the blocks are let go, block 1 is observed to have a velocity of 4.4m/s to the left. What is the speed of block 2?
A 6.0 ✕ 104 kg space probe is traveling at a speed of 12000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 3.0 ✕ 105 N over a distance of 2400 km. What is the final speed of the probe? m/s
You find yourself stuck in outer space with nothing but your physics book and a space suit. You have a mass of 91 kg in your suit, and your physics book has a mass of 2.3 kg. In order to make it back to your stationary spaceship before running out of air, you must move at 0.18 m/s. How fast (in m/s) do you have to throw your physics book to achieve this speed?
Block A (with mass 10 kg) slides along a frictionless floor with a speed of 0.75 m/s and collides with Block B (with mass 12 kg) which was at rest and is attached to a spring with spring constant 24 N/m. The blocks stick together after the collision; what is the maximum compression of the spring?
6) Consider an atomic nucleus that's moving at a speed of 500m/s. This nucleus emits an alpha particle (=nucleus of a Helium atom) in the direction of its velocity, and the new nucleus (produced by the emission of the alpha particle) slows to 450m/s. If the alpha particle has a mass of 4u and the original nucleus has a mass of 208u, what speed does the alpha particle have when it is emitted? (Here u is the atomic mass unit. You could take for u the value of the proton mass, i.e. u= m, = 1.67 × 10-27kg.)
An object is moving so that its kinetic energy is 135 J and the magnitude of its momentum is 31.1 kg m/s. Determine the mass of the object. Use g=9.8
Our brave astronaut Ms. Rose Noneck is at rest spacewalking 9.3 m away from her spaceship when her jetpack runs out of electricity (powered by TCC?). And worst – she is down to 60 seconds of oxygen left – there's plenty in her spaceship as well as her delicious lunch of baba ganoush. She remembers Prof. P's class and throws her 23.6 kg jetpack in the opposite direction of her spaceship at 1.4 m/s. Her mass is 55 kg. Will she make it back to her spaceship before she runs out of air? Convince me with numbers - tell me how long in seconds it takes for her to get back. Will we be seeing her in Exam 4? Or is it the end for her?
Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 4.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle? (a) particle A --------- J(b) particle B --------- J
