When a stick is released (as shown in the figure below), its free end velocity when it strikes the ground is:
1. 4.2 m/s
2. 1.4 m/s
3. 2.8 m/s
4. m/s
1. | \(1.5\) m | 2. | \(2\) m |
3. | \(2.5\) m | 4. | \(3.0\) m |
Consider a system of two particles having masses m1 and m2. If the particle of mass m1 is pushed towards the mass centre of particles through a distance 'd', by what distance would the particle of mass m2 move so as to keep the mass centre of particles at the original position ?
1.
2. d
3.
4.
