SUMMARY
The discussion centers on calculating the time it takes for two bricks, with weights of 24.5 N and 36.8 N, to come to rest under a friction force of 5.0 N. The initial speed of the bricks is 1.77 m/sec. Using Newton's 2nd Law, the acceleration can be determined by applying the formula F = ma, where the net force is the friction force acting against the motion of the bricks. The calculated acceleration will then allow for the determination of the time until the bricks stop moving.
PREREQUISITES
