Question

A race car accelerates from 0.00m/s to 40.0m/s with a displacement of 50.0m. What was the cars

acceleration?

Answer 1

Step-by-step explanation:

Using the equation of motion v² = u²+2as

v is the final velocity = 40m/s

u is the iniyail velocity 0m/s

a is the acceleration

s is the displacement

Substituting in the formula;

40² = 0²+2a(50)

1600 = 100a

Divide both sides by 100

100a/100 = 1600/100

a = 16

Hence the car acceleration is 16m/s²
