1. A trolley A of mass 1.0 kg is moving at 2.0 m/s. It collides with a stationary trolley B of mass 2.0 kg.
Trolley B moves off at 1.2 m/s
[Use the principle of conservation of momentum to calculate the speed of the trolley A after the collision
and state of its direction.]

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
