Answer:
18m/s
Explanation:
Force=30N,mass=10kg
F=ma
30=10×a
a=30÷10=3
a=3m/s, t=1sec,intial velocity (u) =15m/s
v=u+at
v=15+3(1)
v=15+3=18
therefore velocity after 1 second is 18m/s.

Answer :
Mass of body = 10kg
Initial velocity = 15m/s
Applied force = 30N
Time interval = 1s
We have to find final velocity of body after the given interval of time
◈ Newton's Second law of motion :-
As per this law, force is defined as the rate of change of linear momentum.
Momentum is defined as the product of mass and velocity.
- F = m (v - u) / t
⇒ F = m (v - u) / t
⇒ 30 = 10 (v - 15) / 1
⇒ 3 = v - 15
⇒ v = 18 m/s
