Question

A 7.0-kg bowling ball experiences a net force of 5.0 N. What will be its
acceleration?
A. 35 m/s?. B. 7.0 m/s? C.5.0 m/s
D.0.71 m/s​

Answer 1

Answer:

F = ma

5 = 7 x a

a = 5/7

a = 0.71 m/s2

Answer 2

Given :

• Mass (m) = 7.0 kg or 7 kg
• Force (F) = 5.0 N or 5 N

To find :

• Acceleration (a)

According to the question,

→ Force = Mass × Acceleration

Or,

→ F = ma

→ Substituting the values,

→ 5 = 7 × a

→ 5 ÷ 7 = a

→ 0.71 = a

.°. The acceleration is 0.71 m/s²..

So,the correct option is D) 0.71 m/s²

More details :-

• Newton's second law of motion gives us the relationship between the force applied to a body and the acceleration produced in the body.

• Newton's second law of motion :- The rate of change of momentum is directly proportional to the applied force,and takes place in the direction in which the force acts.

• SI unit of Mass is kilograms (Kg).

• SI unit of Acceleration (a) is m/s².

• SI unit of Force (F) is Newton (N).
