... Before we can solve for power we have to convert the time (25 min) into seconds: t = 25 min X 60 sec/min = 1,500 sec Now solving for the power: P = W/t = 253,820 J/1500 sec = 169 w (watts) 24. A boy throws a 4-kg pumpkin at 8 m/sec to a 40-kg girl on roller skates, who catches it. At what speed does ...

... However there are many instances when a moving object is subject to a changing force – can we still calculate future position and velocity? Well, we can if we can quantify the force, i.e. if we know how the force is changing. One example of an object experiencing a changing force is a stretched spri ...
