Essential GCSE physics 20.4 HELP ME PLSS I BEG !!
Two trolleys are at rest and in contact on a smooth, level surface. A coiled spring in one trolley is released so that they 'explode' apart. The lighter trolley (2kg)moves off at 50cm/s. The other trolley (5kg) moves off at 20cm/s.
Find the minimum energy which was stored in the coiled spring before the release. [Hint: see Kinetic energy]
pls can somebody, anybody help me!! Momentum is plaguing my nightmares

You're going to add together the KE of the 5kg trolley and the KE of the 2kg trolley.
Thank you, I think I was overthinking it lol. The answer is 0.35
