A racing car moving at 59.9 m/s engages a parachute and braking system. It comes to rest 4.21 s later. Determine the value (magnitude) of the acceleration of the car. (No +/- signs.)

Answer :

The magnitud of the acceleration of the car moving with a velocity of 59.9 m/s is 14.23 m/s².

What is acceleration?

Acceleration can be defined as the rate of change of velocity.

To calculate the acceleration of the car, we use the formula below

Formula:

  • a = (v-u)/t......... Equation 1

Where:

  • a = Acceleration of the car
  • v = Final velocity of the car
  • u = Initial velocity of the car
  • t = time

From the question,

Given:

  • v = 0 m/s (To rest)
  • u = 59.9 m/s
  • t = 4.21 s

Substitute these values into equation 1

  • a = (0-59.9)/4.21
  • a = 14.23 m/s²

Hence, the acceleration of the car is 14.23 m/s².
