Question

Question 1: An object of 50 kg gets the speed of 10m/s in 5 second from zero velocity. Calculate the required force applied by engine of the car.

Answer 1

Answer:

Explanation:

F=ma

m=mass of object

a=acceleration produced by the object

Given,

Final velocity (v) =10m/s

Initial velocity (u)=0m/s (as the car start s from rest)

Time(t)=5s

Acceleration =v-u/t

10-0/5=2m/s²

Force=50×2=100N

FORCE=100N

Answer 2

Answer:

Force = 100 N

Explanation:

Force = mass*acceleration

Mass = 50 kg

Initial velocity (u) = 0m/s

Final Velocity (v) = 10m/s

Time (t) = 5s

Acceleration = $\frac{v - u}{t}$

                     = $\frac{10 - 0}{5}$

                     = 2m/s²

Hence, Force = 50*2

Force = 100 N
