calculating acceleration

Question 1

What is another formula to calculate the acceleration?

Answer 1

a = f/m

Question 2

A forward force produced by the car is 2500N. Calculate the acceleration when the mass of the car is 500kg

Answer 2

2500/500 = 5 m/s squared

Question 3

A cheetah accelerates from 10 m/s to 25 m/s in 3 seconds. Calculate its acceleration.

Answer 3

20-10/3 = 5 m/s squared

Question 4

what is significant about the force in this formula a = f/m?

Answer 4

the f stands for the resultant force
