These are “plug-in-the-number” type activities to familiarize yon with the equations that link the concepts of physics. They are mainly one-step substitutions and are less challenging than the Problem. ? Calculate the acceleration of a bus that goes from 10 km/h to a speed of 50 km/h in 10 seconds.

Answer: Acceleration= Rate of change of Velocity / time Step 1:So here , Initial velocity = 10 km/hour Final velocity = 50 km/hour In Time = 10 seconds
