At what speed is a particle moving if the mass is equal to three times its rest mass.
Data `m=3m_(0)`, v = ?

Text Solution

Verified by Experts

`m=(m_(0))/(sqrt(1-(v^(2))/(c^(2))))`
`3m_(0)=(m_(0))/(sqrt(1-(v^(2))/(c^(2))))`
v=0.943C
`=0.943xx3xx10^(8)`
`v=2.829xx10^(8)ms^(-1)`

A particle of mass m moving in the x direction with speed 2v is hit by another particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to :

An explosion blows a rock into three pieces. Two pieces go off at right angles to each other. One of these two pieces of mass 1 kg moves with 12 m//s and other of mass 2 kg moves with 8 m/s. If the velocity of the third piece is 40 m//s, then its mass is:

A body of mass m moving along a straight line covers half the distance with a speed of 2ms^(-1) . The remaining half of the distance is covered in two equal time intervals with a speed of 3ms^(-1) and 5ms^(-1) respectively. The average speed of the particle for the entire journey is
