6Answer: Velocity after 5sec will be 25m/s
Explanation:
Given - FORCE (F) = 50N
MASS (M) = 10kg
To find - Velocity(V) of the body after 5sec = ?
Solution -
Force(F) acting on a body of mass(M) moving with Acceleration(A) is given by
F = M*A...........(i)
In this case
F = 50N AND M = 10kg ( All quantities are in S.I unit )
Therefore by equation (i) we have
50 = 10*A
A = 50/10
this implies
A = 5 m/s^2
Since we know that for constant acceleration of a body it is given by
A = V - U/T .......( ii)
( where A is the acceleration , V is the velocity at the given time and U is the initial velocity and T is the given time)
In this case
A = 5 m/s^2 , T = 5 sec , U = 0 ( cause body starts from rest) , V = ?
By (ii) we have
5 = V - 0/ 5
V = 5 * 5
This implies that
V = 25 m/s
Hence , Velocity of the body after 5 secs of motion is 25 m/s.
