Answer:

Using Newton’s 2nd law

Ft=m(v-u)

m=50*0.2/10

m=10/10

m=1kg

Explanation:

By using Newton's second law, the mass of the object is 1kg

FORCE

The force on an object is a push or pull effect.

Given that a force of 50 N is applied to an object for 0.2s , and it

changes its velocity by 10m/s. The parameters are;

  • Force F = 50 N
  • Time t = 0.2 s
  • Change in Velocity = 10 m/s
  • Mass m = ?

From first linear equation of motion,

V = U + at

V - U = at

Where V - U = change in velocity = 10 m/s

Substitute it and time t into the equation.

10 = 0.2a

a = 10/0.2

a = 50 m/[tex]s^{2}[/tex]

From second Newton's law, F = ma

Substitute the force and the acceleration into the formula

50 = 50m

m = 50/50

m = 1 kg

Therefore, the mass of the object is 1kg.
