If an object has a mass of 93 kg, the coefficient kinetic friction between the object and a ramp is 0.16, and the ramp angle is 54, what is the net force? A graph of v(t) is shown for a world-class track sprinter in a 100-m race. What ...
A 47.0-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of-1.97 m/s. Her hands are in contact with the wall for 1.17 s. Ignore friction and wind resistance....
