Answer 2

Answer:

The final velocity of the body is 6m/s

Explanation:

We know that,

Mass - m = 10kg

Initial velocity - u = 1m/s

Force - f = 50N

The force is given as,

F = ma

50 =  10 × a

50 ÷ 10 = a

a = 5m/s²

The final velocity is given as,

v = u + at

v = 1 + 5 × 1

v = 1 + 5

v = 6m/s

The final velocity of the body is 6m/s
