following situations: a. a 90 kg football player running at 6 m/s b. a 1500 kg car moving at a rate of 100 km/h c. a 200,000 kg Boeing 777 moving at a speed of 500 km/h d. a bullet with a mass of 15 g traveling at a speed of 500 m s/ e. a 140 g baseball traveling at 120 km/h f. an 80 kg stunt performer falling off a tenstory
Compute the values of momentum for the
following situations:
a. a 90 kg football player running at 6 m/s
b. a 1500 kg car moving at a rate of
100 km/h
c. a 200,000 kg Boeing 777 moving at a speed
of 500 km/h
d. a bullet with a mass of 15 g traveling at a
speed of 500 m s/
e. a 140 g baseball traveling at 120 km/h
f. an 80 kg stunt performer falling off a tenstory building reaching a speed of 30 m
We know momentum of a body of mass 'm' and moving with velocity ' v ' is given by
P = mv
(a) momentum ( P ) = mv = 90×6
= 540 kg - m/s
(b) P = mv = 1500 × 100 kg - km/h
=150000 kg - km/h
= 41666 .67 kg-m/s
(c) P = mv = 200000 × 500 kg - km/h
= 100000000 kg - km/h
= 27777777.77 kg - m/s
