Question

A body starts sliding on a rough horizontal surface with a speed of 10 m/s. if the
coefficient of friction is 0.2; find the distance traveled by the body before coming to
rest. (g 10 m/s)
A., 15 m
D. 40 m
E. 55 m​

Answer 1

Answer:

25 m

Explanation:

Stopping distance is calculated by

• S = u²/(2μg)

Where

• S = Stopping distance
• u = Initial velocity
• μ = Coefficient of friction
• g = Acceleration due to gravity

S = (10 m/s)² / (2 × 0.2 × 10 m/s²)

= (100 m²/s²) / (4 m/s²)

= 25 m
