Name the physical quantity obtained by dividing ‘Distance travelled’ by ‘Time taken’ to travel that distance.
A motorcyclist starts from rest and reaches a speed of 6 m/s after travelling with uniform acceleration for 3 s. What is his acceleration ?
Convert a speed of 54 km/h into m/s.
When is a body said to be in motion?
Which of the quantity-velocity or acceleration-determines the direction of motion?
A train is moving with a velocity of 90 km h-1 . It is brought to stop by applying the brakes which produce a retardation of 0.5 ms-2 Find :
(i) The velocity after 10 s , and
(ii) the time taken by the train to come to rest .
What is the relation between distance and time when the body is moving with uniform velocity?
Draw a diagram to show the motion of a body whose speed remains constant, but velocity changes continuously.
A speeding car changes its velocity from 108 kmh−1 to 36 kmh−1 in 4 s. Calculate its deceleration in
- ms−2
- kmh−2.
A body projected vertically up with a velocity of 10 m/s reaches a height of 20 m. If it is projected with a velocity of 20 m/s, then the maximum height reached by the body is:
