00:00 Introduction: Motion - Numerical Problems of Motion
01:04 Numerical Problems of Motion: Que. 1 - A scooter acquires a velocity of 36 km per hour in 10 seconds just after the start. Calculate the acceleration of the scooter.
09:26 Que. 2 - A moving train is brought to rest within 20 seconds by applying brakes. Find the initial velocity, if theretardation due to brakes is 2 ms^-2
13:25 Que. 3 - A body starts to slide over a horizontal surface with an initial velocity of 0.5 m/s. Due to friction, its velocity decreases at the rate of 0.05 m/s2 (acceleration, -0.05 m/s2). How much time will it take for the body to stop?
17:40 Que. 4 - A racing car has a uniform acceleration of 4 m/s2, What distance will it cover in 10 seconds after the start?
20:11 Que. 5 - A scooter moving at a speed of 10 m/s is stopped by applying brakes which produce a uniform acceleration of, -0.5 m/s2. How much distance will be covered by the scooter before it stops?
22:40 Que. 6 - A car travelling at 20 km/h speeds up to 60 km/h in 6 seconds. What is its acceleration?
29:52 Que. 7 - A bus increases its speed from 20 km/h to 50 km/h in 10 seconds. Its acceleration
