​

Answer 1

CORRECT QUESTION:

A force of 10N is applied on a mass of 2kg for 2 seconds. Calculate it's Velocity and Momentum after 2 seconds.

ANSWER:

velocity (v) = 10 m/s

Momentum (p) = 20 kgm/s

GIVEN:

F = 10 N

m = 2 kg

t = 2 s

u = 0

TO FIND:

velocity (v) = ?

Momentum (p) = ?

FORMULAE:

a = F/m

v = u + at

p = m (v-u)

EXPLANATION:

a = 10/2

a = 5 m/s²

v = 0 + 5(2)

v = 10 m/s

p = 2(10 - 0)

p = 20 kgm/s

velocity (v) = 10 m/s and Momentum (p) = 20 kgm/s.
