Astudent 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 ?

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

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
