Question

i know it's pretty much long but if u tell me 1 answer that will be helpful !​

Answer 1

Answer:

11 Ans. M1 =M2=1.50kg

V1=2.50m /sec

V2=2.50m/sec( opposite direction)

We know,

M1 +m2v2= (m1+m2)

1.50×2.50-1.50× 2.50=(1.50+1.50)v

0 =3v

V=0

So, the combined momentum is zero

9 Ans. mv

Explanation.

Mass of the object = m

Velocity = v

Momentum = Mass ×Velocity Momentum = mv

Answer 2

Answer:

3• When a bus travels, its motion cannot be uniform in practice. ... If any luggage kept on the roof of the bus is not tied with a rope, then it tends to move forward due to its inertia. In this process, it could fall off the bus. Therfore, it is advised to tie any luggage kept on the roof of a bus with a rope.
