Question

a body of mass 1kg moves with velocity 10i m/s. it is given as impulse such that velocity becomes 10j m/s then magnitude of impulse is​
need answer fast

Answer 1

Answer:

10√2

Explanation:

Since Impulse change = Change in Momentum

so Impulse = ΔP

or

Impulse = mΔv = m(v2 - v1 )

Impulse = 1kg ( 10 j - 10 i ) m/s

Impulse is a vector quantity and J and I gives you the directions.

If you'll draw the corresponding vectors in their direction and join by head to tail, you gonna get

hyp = √ base² + per ²

hyp = √ 10² + 10²

hyp = 10√2

So Impulse = 1 (10√2) Kg m /s
