Question

a police van moving with the speed of 36km/hr chasing a car moving with the speed of 216km/hr.if the muzzle speed of bullet is 150m/s,with what speed the bullet hits the car?

Answer 1

HEY MATE HERE'S YOUR ANSWER
AS GIVEN ABOVE
SPEED OF POLICE CAR = 36KM/H
SPEED OF ANOTHER CAR = 216KM/H
THEN SPEED OF RELATIVITY = 180KM/H
= 180×5/18 = 50m/s
NOW AS THE SPEED OF BULLET = 150M/S
THEN THE SPEED FROM WHICH IT WILL HIT
= 100M/S (150-50 FROM RELATIVITY )
HOPE IT HELPS YOU

Speed of the police van,

v(p) = 30 km/h = 8.33 m/s

Muzzle speed of the bullet,

v(b) = 150 m/s

Speed of the thief’s car,

v(t )= 192 km/h = 53.33 m/s

Since the bullet is fired from a moving van, its resultant speed can be obtained as: = 150 + 8.33 = 158.33 m/s

Since both the vehicles are moving in the same direction, the velocity with which the bullet hits the thief’s car can be obtained as: v(bt) = v(b) – v(t)= 158.33 – 53.33 = 105 m/s

I hope, this will help you
