A archer, standing on frictionless ice, shoots a arrow at a speed of . What is the recoil speed of the archer?
The recoil of the archer is
we have given,
we have to find the recoil speed of the archer.
When two particles collide and stick together and move as one body then it will be inelastic collision where only momentum will be conserved.
Since initially the archer and the arrow is at rest then the initial momentum and final momentum will be zero.
It means that the magnitude of momentum of archer will be equal to the magnitude of the momentum of arrow and opposite in direction.
In FIGURE P11.57, a block of mass m slides along a frictionless track with speed . It collides with a stationary block of mass M. Find an expression for the minimum value of that will allow the second block to circle the loop-the-loop without falling off if the collision is (a) perfectly inelastic or (b) perfectly elastic.
