Question

Calculate the ratio of momentum when velocity is doubled mass of an object is halved and both mass and velocity are increased by three times

Answer 1

What is the ratio of momentum when the velocity of an object is doubled and mass of an object is halved?

Since P=mv

If P1=mv

Then P2 =m/2*2v=mv

So P1=P2 & P1:P2=1

Momentum (p) is the product of velocity (v) and mass (m).

p = mv

So, if you double v and halve m, the net change is zero.

p=m/2×2v

p=mv×2/2

p=mv

Kinetic energy, though, would increase.

Answer 2

HEY MATE UR ANSWER IS
p=mv

if p1= mv

Then p2 =m/2*2v=mv

So p1= p2 & p1:p2

Momentum(p) is the produce of velocity (v) & mass( m)

p= mv

so if you double v and Halve and the net change is zero

p= m/2×2v

P= mv×2/2

P= mv

kinetic energy thought would increase

I THINK IT HELPS U
