# CBSE Class 9 Physics Equations Of Motion

## Sample Q&A

- Derive an equation for position -time (S=ut+1/2at^2) relation for an object that travelled a distance 's' in time 't' under uniform acceleration 'a'
- a train is moving with an initial velocity of 30 metre per second the brakes are applied so as to produce a uniform acceleration of -1.5 metre per second square calculate the timeuniforma uniform acceleration
- an object is moving with a velocity 5m/s find the distance travelled in 5sec if the object is accelerating with a uniform acceleratrion of 5 m/s
- A body is thrown vertically upward with velocity u, the greatest height h to which it will rise is
- what is nth second of motion
- A car starts from the rest and accelerates at the rate of 5m/s2. It continue accelerating for 10 s and then move at constant velocity for next 10 s. Calculate the total distance traveled by the car in 20s. (5)
- A car is coasting backwards down a hill at -3.0 m/s when the driver gets the engine started. After 2.5s, the car is moving uphill at a velocity of +4.5 m/s. What is the car's acceleration?
