A motorcycle of mass m resting on a frictionless road moves under the influence of a constant force F. The work done by this force in moving the motorcycle is given by F 2 t 2 /2m, where t is the time in seconds.
Ratio of instantaneous power to average power of the motorcycle in t = T second is
Text Solution
Verified by ExpertsThe correct answer is:
B
For instantaneous power
dP = 
or dP= 
But average power = 
∴ ∴ Instantaneous power: average power = 2 : 1.
