Question

a force of 50N acts on a mass of 12.5 kg for 4 seconds. To calculate it's vilocity .​

Answer 1

Answer:

Force = Mass × acceleration.

50N = 12.5 × a

a = 50 / 12.5

a = 4

$a \: = 4 \: \frac{m}{ {s}^{2} } \\ v = u + at \\ v = at \\ v = 4 \times 4 \\ v = 16 \frac{m}{s}$

Answer 2

F=ma

50/12.5=a=4ms^2

V=a×t=16ms^1
