Question

A car accelerates from 55 to 88 m/s in 6 seconds. Calculate the average acceleration (a).

What is the distance travelled?

Answer 1

The average acceleration of the car is 5.5 m/s^2 and the distance traveled is 429 m.

Step-by-step explanation:

To calculate the average acceleration, we use the formula:

a = (vf - vi) / t

where
vf = final velocity = 88 m/s
vi = initial velocity = 55 m/s
t = time = 6 s

Substituting the given values, we have:
a = (88 - 55) / 6 = 33 / 6 = 5.5 m/s^2

To find the distance traveled, we can use the formula:
d = (vf + vi) / 2 * t

Substituting the given values:
d = (88 + 55) / 2 * 6 = 143 / 2 * 6 = 429 m
