How much force is exerted if a 250 kg object has an acceleration of 750 m/s\(^2\)?

Question 9 options:

A. 0.33 N

B. 187,500 N

C. 3 N

D. None of the above

Answer :

Use Newton’s second law: F=ma
m= 250kg. a= 750ms-2
F= 250 x 750 = 187 500N

Answer:

The correct option is B which is 187,500 N.

Explanation:

According to the second law of motion, if a considerable amount of force is exerted on an object of mass,it will produce acceleration in the object.

F = ma.

By putting values from question in the above formula:

F = 250 kg × 750 m/s2

F = 187,500 Kg.m/s2.

Kg.m/s2 is equal to 1 newton which is the unit of force.

Hence the correct option is B which is 187,500 N.
