3.5 Newton of force is needed to accelerate 140g of ball at 25 m/s^2 using the formula f=ma
Change 140g to kg
Answer:
f. Force acting down and constant
Explanation:
At the highest point, the coin will start to free fall and in free fall only force of gravity act, which is always acted downward and its magnitude is mass times g. g=9.81 m/s^2. which makes the force constant.
therefore, the correct answer will be f. Force acting down and constant
