Question

has a soccer ball and a kickball. She kicks each ball with the same force. The soccer ball accelerates at 3 m/s2, and the kickball accelerates at 5 m/s2. Use Newton’s laws to describe why the kickball has a greater acceleration.

Answer 1

Answer:

Kick ball has  a great acceleration because mass of kick ball is smaller than the mass of soccer ball.

Explanation:

We are given that there are two balls a soccer ball and  a kick ball.

Applied force on each ball is same.

Acceleration of soccer ball=$3m/s^2$

Acceleration of kick ball=$5m/s^2$

We have to find why lick ball has a greater acceleration.

We know that $Acceleration=a=\frac{f}{m}$

where f=force applied on object

m=Mass of object

Acceleration depends upon force and mass.

But force remain same, then the acceleration depends upon mass only.

Acceleration is inversely proportional to mass .If mass of object is large then the acceleration is small and when mass is small then acceleration is large.

Therefore, Soccer ball acceleration is smaller than the acceleration of kick ball.It means mass of soccer ball is larger than the mass of kick ball.

Kick ball has  a great acceleration because mass of kick ball is smaller than the mass of soccer ball.

Answer 2

F=ma a=f/m kickball weighs 3kg and soccer ball weighs 5kg and she kicked with a force of 15n  15/3=5    15/5=3 so since the weight is different the acceleration is different
