Question

a 3000 kg car accelerates uniformly from 15 m/s to 60 m/s in 5 seconds. determine the net force on the car during this time ​

Answer 1

F = 2700 N

Step-by-step explanation:

Given that,

Mass of a car, m = 3000 kg

Initial velocity, u = 15 m/s

Final velocity, v = 60 m/s

Time, t = 5 s

We need to find the net force on the car during this time ​. The net force on an object is given by the product of mass and acceleration. So,

F = ma

a is acceleration, a = (v-u)/t

`F=(m(v-u))/(t)\\\\F=(3000* (60-15))/(5)\\\\F=27000\ N`

So, 27000 N is the net force on the car during this time .
