Teaching HTET PGT Level 3 - 2024 Mock Test Physics Work Power and Energy Conservation of Mechanical Energy
Power of an object of mass 2 kg is \(P =\frac{ 3t^2}{2} \) where t is the time in second. If the velocity of particle at t = 0 is 1 m/s, the velocity of particle at t = 2 s will be-
1
√5 m/s
2
2 m/s
3
1.3 m/s
4
0 m/s
