Assume a spaceship heading directly away from Earth at 0.610c can shoot a canister at 0.460c relative to the ship.
A) Obtain the velocity of the canister relative to the Earth, if it is shot directly at the Earth?
B) Obtain the velocity of the canister relative to the Earth, if it is shot directly away from the Earth?
A uniform beam having a mass of 60 kg and a length of 2.8 meter isheld in place at its lower end by a pin. Its upper end leansagainst a vertical frictionless making an angle of 40 degrees withthe horizontal. What is the magnitude of the force by t..
A 210-kg crate is being pushed across a horizontal floor by aforce P that makes an angle of 18.6° below the horizontal. The coefficient of kinetic friction is0.209. What should be the magnitude of P, so that the net work done by it and the kinetic..
