Question

An object with uniform acceleration of 2 m/s ^2 is moving with a velocity of 20 m/s. After 10 seconds ______ will be its velocity.​

Answer 1

Answer:

Explanation:

This one is the most simplest questions you can get in rectilinear motion.

So here:initial velocity (U)=10 m/s, Final velocity(V)=?, Acceleration(a)=m/s^2, Time(t)=4 seconds.

Therefore putting it in the equation: V=U+at, we get

V=10+2*4= 18

i.e. the final velocity is 18 m/s.
