Define velocity. What is the SI unit of velocity ?
Name the quantity which is measured by the area occupied under the velocity-time graph.
A motorcycle moving with a speed of 5 m/s is subjected to an acceleration of 0.2 m/s2. Calculate the speed of the motorcycle after 10 seconds, and the distance travelled in this time.
A car is travelling along the road at 8 ms-1. It accelerates at 1 ms-2 for a distance of 18 m. How fast is it then travelling ?
A bus increases its speed from 36 km/h to 72 km/h in 10 seconds. Its acceleration is :
The slope of a speed-time graph gives:
Define velocity. State its unit.
A car starting from rest acquires a velocity 180m s-1 in 0.05 h. Find the acceleration.
A body is thrown vertically upward with velocity u, the greatest height h to which it will rise is,
An electron moving with a velocity of 5 × 104 ms−1 enters into a uniform electric field and acquires a uniform acceleration of 104 ms–2 in the direction of its initial motion.
(i) Calculate the time in which the electron would acquire a velocity double of its initial velocity.
(ii) How much distance the electron would cover at this time?
