what force is needed to give a 4.5 kg bowling ball an acceleration of 9 m/s^2
Answer: 40.5 N
Explanation:
Newton's second law states that the force applied to an object is directly proportional to the acceleration of the object, following the relationship
\(F=ma\)
where
F is the force applied
m is the mass of the object
a is the acceleration
In this problem, we have
m=4.5 kg is the mass of the bowling ball
\(a=9 m/s^2\) is its acceleration
Therefore, the force applied on the ball is
\(F=ma=(4.5 kg)(9 m/s^2)=40.5 N\)
