- 4.0 m/s 3.0 kg A 3.0 kg cart is moving at a speed of 4.0 m/s to the right across a frictionless table, as shown above. It collides with a second cart of an unknown mass m that is initially at rest. The magnitude of the force F of the collision as a function of time t is shown in the graph below, wheret = 0 is the instant of initial contact. As a result of the collision, the second cart acquires a speed of 1.6 m/s to the right. Assume that friction is negligible before, during, and after the collision. 10 Force (N) 1.0 2.0Thank you!11.
