A bullet fired into a fixed target loses half of its velocity after penetrating 3 cm. How much further will it penetrate before coming to rest?
A person standing on the edge of a cliff throws one ball vertically upwards and another ball vertically downwards with the same speed. Which ball hits the ground with greater speed?
A particle starts from rest and moves with an acceleration that increases linearly with time as a = kt. The velocity after time 't' will be:
A body covers 12m in the 2nd second and 20m in the 4th second. How much distance will it cover in 4 seconds?
What is the angle between velocity and acceleration in a uniform circular motion?
A tap drips at a rate of 1 drop per second. What is the distance between the 1st and 2nd drops when the 1st drop has been falling for 3 seconds? (g=10 m/s^2)
A ball is thrown horizontally from a height of 20m with a velocity of 5 m/s. Where will it land relative to the tower? (g=10 m/s^2)
The velocity of a particle at any time t is given by v = 2t(3-t). At what time is the velocity maximum?
A stone is dropped from a height. If it covers the last 44.1m in the last second, find the total time of fall. (g=9.8 m/s^2)
Which of the following speed-time graphs represents a body whose speed is decreasing linearly?
A car travels half of the distance at speed v1 and the other half at speed v2. The average speed is:
If air resistance is taken into account for a ball thrown upwards, the time of ascent is ______ the time of descent.
What is the magnitude of acceleration for an object moving with velocity v = 5t^2 + 2t at t = 1s?
A body is dropped from a height H. The time taken to cover the second half of the height is:
If a body travels with uniform acceleration, the graph of 'v^2' against 's' is a:
