object 142. What is the magnitude of the net force acting on a 2.0 x 10³-kilogram car as it accelerates from rest to a speed of 15 meters per second in 5.0 seconds? (1) 6.0 x 10 N (2) 2.0 x 10° N (3) 3.0 x 10ª N (4) 6.0 x 104 N 143. A 5.00-kilogram mass is traveling at 100. meters per second. Determine the speed of the mass after an impulse with a magnitude of 30.0 newton • seconds is applied.
