A 1000-kg car moving at 10 m/s brakes to a stop in 5 s.The average braking force is

Question

Quizplus · Accepted Answer

The average braking force can be calculated using the formula: Force = mass × acceleration. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Here, the initial velocity is 10 m/s, the final velocity is 0 m/s, and the time is 5 s. So, acceleration = (0 - 10) / 5 = -2 m/s². The force is then 1000 kg × (-2 m/s²) = -2000 N. The magnitude of the force is 2000 N.
