A 1.0 Kg object, A, with a velocity of 4.0ms-1 to the right, strikes a second object, B, of mass 3.0 Kg, originally at rest. In the collision, A is deflected

from its original direction through an angle of 50°; its speed after the

collision is 2.0ms-1. Find the angle between B’s velocity after the collision

and the original direction of A, and find the speed of B after collision​

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

What is the single most important equation in all of physics?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
