Object 1 has a mass m1 and a velocity v1 = (2.50 m/s )x^. Object 2 has a mass m2 and a velocity v2 = (3.00 m/s )y^. The total momentum of these two objects has a magnitude of 20.0 kg⋅m/s and points in a direction 65.0 ∘ above the positive x axis. part a find m1.part b Find m2.

What is the maximum acceleration of the wing tips, in units of g?

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

What are similarities and differences between refraction, reflection, diffraction and absorption?
