Question

A car starts from rest and has a uniform acceleration of 2m/s sq. Find the speed of car after 5 seconds.

Answer 1

Answer:

10m/s

Step-by-step explanation:

The final velocity(velocity after 5 sec) will be 10m/s

We will use the equation of motion,

》vf=vi +at

Here vf is the final velocity and vi is the initial velocity.

●Given Data:

Vi=0 m/s

Acceleration=a=2 m/s^2

Time=t=5 sec

●Required:

Vf=?

●Calculation:

》vf=0+(2×5)

》vf=10 m/s

Answer 2

Answer:

10ms

Step-by-step explanation:

u=0 a=2ms? V=u+at So,0+2*5=10 Therefore,speed of the vehicle after 5's= 10ms
