Question

a body starts to move from rest and with uniform acceleration 1.6 metre per second square calculate the final velocity and distance travelled by the body in 2 minutes​

Answer 1

Explanation:

Here,

initial velocity (u)= 0

acceleration (a)= 1.6m/s^2

time taken (t)= 2minutes=2×60 sec = 120s

final velocity (v)=?

displacement(s)=?

we know that

a= (v-u)/t

1.6 =v-0/120

1.6×120=t

v=192m/s^2

again,

s=ut+1/2 at^2

use this formula and find the distance travelled
