Question

A drag racing vehicle travels from 0 100 mph in 5 seconds north. What is the acceleration ​

Answer 1

The formula to find accerelation is:

Accerelation= change in velocity÷change in time

the change in velocity here is: 100mph

the change in time is: 5 seconds

a=100÷5 ms

a= 20ms-2

Answer 2

8.94m/s²

Step-by-step explanation:

Acceleration is defined as the change in velocity of an object with respect to time. Mathematically,

Acceleration (a) = change in velocity(∆v)/time (t) where;

Change in velocity(∆v) = final velocity (v) - initial velocity (u)

a = ∆v/t = v-u/t

Given v = 100mph u = 0mph since the vehicle travels from 0mph to 100mph, t = 5seconds

Since 1mph = 0.447m/s

100mph = 44.7m/s

Substituting this values in the formula given we have;

a = 44.7-0/5

a = 8.94m/s²

Its acceleration is 8.94m/s²
