What is the velocity of the stone when the man catches it?
When the acceleration of the object is larger than 10 m/s2
When the net resultant force acting on the object is zero
A trolley at the middle of a frictionless slope is given an initial push up the slope. It moves up, and then rolls back down. Sketch the velocity time graph of the trolley and indicate how the displacement of the trolley can be found using the graph.
A car starts from rest and moves with increasing acceleration for 10s. It then moves with a constant velocity of 80 km/h before slowing to a stop with constant deceleration of 15km/h2.
Sketch the velocity-time graph of the car’s motion
Sketch the displacement-time graph of the car’s motion
