Therefore, resistance of bulb will be 1210 ohm
Divide distance by the time it takes to travel that distance
the formula for time is divide distance/speed
When a force is applied to the box , this will cause an acceleration to the box.
(force =mass×acceleration)
So the box has a constant acceleration and a changing velocity.
