Question

An objects has constant momentum of 2.45x102 kg m/s. Determine the momentum of the object if it’s mass decreases to 1/3 of its original value and applied forces causes the speed to increase to exactly four times of the original... The direction of the velocity remains the same...

Solution

momentum(p)
= mass× velocity
= 245 kg m/s.
Now, mass decreases to 1/3 of its original value &
velocity becomes 4 times.
therefore ,
new momentum
p'=1/3 mass×4× velocity
=4×1/3×mass× velocity
=4/3×p
=4/3×245
= 326.666667kg m/s.
