a particle of mass 3m is moving with 20 root 2 m/s velocity by making 45 degrees with horizontal is explodes into two parts are moving in opposite direction if first particle fall at 100 metres what is the position of second
When the particle explodes into 2, there is no external force so Fnet external is zero. Hence the net momentum in horizontal dirn will be conserved.By this info, we can find hori velocity of second particle and hence the distance travelled.Thanks
