Question

A body moving on a straight line such that at t is equal to zero second u is equal to 5 metre per second and acceleration is equal to minus 1 metre per second square ,speed at t is equal to 10 second is

Answer 1

Answer:

-5 m/s

Explanation:

Given :

• Initial velocity = u = 5 m/s
• Acceleration = a = - 1 m/s²
• Time = t = 10 seconds

To find :

• Final velocity of the body (v)

Using first equation of motion:

V=u+at

Substituting the values :

V=5-1×10

V=5-10

V= - 5 m/s

The final velocity of the body will be equal to - 5 m/s and it will go in the opposite direction of motion as velocity is negative
