A 0.5 kg soccer ball moving at 15 m/s hits a stationary 2 kg wall. If the collision is perfectly elastic, find the ball’s rebound velocity. (Hint: Use relative velocity approach.)
A Dubai Metro train starts from rest at Jebel Ali station, accelerates at 0.5 m/s² for 20 s, then moves at constant speed for 60 s, and finally decelerates at 0.3 m/s² to stop at UAE Exchange station. Find total displacement.
For motion with constant acceleration ( a ), initial velocity ( v_0 ), final velocity ( v ), displacement ( \Delta x ), and time ( t ):
typically sets the stage by moving beyond basic observations into quantitative analysis. Students are expected to not only understand what happens but also calculate how and why it happens using algebraic formulas and vector analysis.
An object at rest stays at rest, and an object in motion stays in motion with constant velocity unless acted upon by a net external force.
