Question

A body of mass 2kg which is at rest is given impulse of 10N-s the body has speed or momentum and how much?

Answer 1

F = m×a
a= 10/2
a=5
speed after 1 sec is 5
and momentum in m delta v
2×5
10

Answer 2

Dear Student,

◆ Answer -

v = 5 m/s

● Explanation -

# Given -

m = 2 kg

u = 0 m/s

Impulse = 10 N/s

# Solution -

Impulse is calculated by formula -

Impulse = m.∆v

Impulse = m × (v - u)

10 = 2 × (v - 0)

2v = 10

v = 10/2

v = 5 m/s

Hence, the body has speed of 5 m/s.

Thanks dear. Hope this helps you...
