Question

You observe a dime (m = 2.3 grams) come to a stop from speed vi = 11.5 m/sec, over a distance Δx = 2.945 m.

Calculate: the average stopping force on the dime.

Type in your answer to the nearest cm. E.g., if your answer is 83.648 m, then type 83.65 in the answer box.

Answer 1

Concept: find the acceleration using equation of kinematics where initial and final velocities and displacement are given. Then use the acceleration to find the force.
