Answer:
Ram has more Power
°•°Mark me as the BRAINLIEST°•°
Explanation:
Both have 40 kg mass
So their weight=40 × 10(Taking g as 10..you can take 9.8 too)
=400 N
weight is also a force
so Force=400 N
Displacement=6m
Work done=Force×Displacement
=400×6=2400 J
Power=Work/Time
Power of Ram=2400/20 Watt
=120 Watt
Power of Shyam=2400/25=96 Watt
Hence Ram has more power
