A student throws a 140 g snowball at 6.5 m/s at the side of the schoolhouse, where it hits and sticks. What is the magnitude of the average force on the wall if the duration of the collision is 0.17 s?

Answer:5.35N

Explanation:

Force is defined as the product of mass of an object and its acceleration.

Acceleration is the change in velocity of an object with respect to time.

Acceleration = velocity / time = 6.5/0.17 = 38.2m/s²

since F = ma and mass is 140g

140g to kg will be 140/1000 = 0.14kg

F = 0.14 * 38.2

F = 5.35N

magnitude of the average force is 5.35N
