Answer :
Final answer:
The force needed to accelerate the ball is 3.5 N.
Explanation:
To calculate the force needed to accelerate the ball, you can use the formula: F = m x a. F represents the force, m represents the mass, and a represents the acceleration. In this case, the mass of the ball is 140 g, which is equal to 0.14 kg. The given acceleration is 25 m/s2. Substituting these values into the formula, we get:
F = 0.14 kg x 25 m/s2 = 3.5 N
Therefore, the force needed to accelerate the ball at 25 m/s2 is 3.5 N.
