If a #12 kg# object is constantly accelerated from #0m/s# to #4 m/s# over 7 s, how much power musy be applied at #t=1 #?
Given: Object mass,
Required: Power applied or use up at
For constant acceleration, the kinematic expression between velocity, acceleration and time is
We know that Force
It is given that during the period acceleration is constant.
Implies that force is also constant during the period.
Let the object move through a distance
Power applied at
