WitrynaNewton’s 2nd Law relates an object’s mass, the net force on it, and its acceleration: Therefore, we can find the force as follows: Fnet = ma. Substituting the values, we get. 1000 kg × 4 m/s 2 = 4000 N. Therefore, the horizontal net force is required to accelerate a 1000 kg car at 4 m/s -2 is 4000 N. Witryna18 wrz 2024 · Solution of Problem 1. A force will cause an acceleration a. a = force/mass = 10/1 m/s^2 = 10 m/s^2. The force acts for 0.1 seconds. That means the body will …
