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.

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
