Question

plzzzzzz solve step by step​

Answer 1

Answer:

v=30m/s

Explanation:

m(v2-v1)= 2000

100(v2-v1)=2000

v2-v1=20

v1=10m/s

v2= 10+20= 30m/s

your welcome

Answer 2

As we know that MASS IS A CONSTANT QUANTITY, so, the value of the mass of the motorcycle will remain fixed, i.e., unchanged.

Initially, the linear momentum of the motorcycle = (100×10) Ns = 1000 Ns

New linear momentum = (1000+2000) Ns = 3000 Ns

So, New velocity = New momentum/Mass = (3000/100) m/s = 30 m/s
