A47 Às shown in the diagram, two trolleys Pand Q
of masses 0.50 kg and 0.30 kg respectively are
held together on a horizontal track against a
spring which is in a state of compression.
When the spring is released the trolleys
separate freely and P moves to the left with
an initial velocity of 6 ms '. Calculate:
(a) the initial velocity of Q,
(b) the initial total kinetic energy of the system.
Calculate also the initial velocity of Q if trolley
Pis held still when the spring under the same
compression as before is released.
