Question 1
The velocity v of a moving particle varies with displacement as x =
, the acceleration of the particle at x = 5 unit will be-
, the acceleration of the particle at x = 5 unit will be- Question 2
Two particles A and B are initially 40 m apart. A is behind B. Particle A is moving with uniform velocity of 10 m/s towards B. Particle B starts moving away from A with constant acceleration of 2 m/s2.
(i) The time at which minimum distance between the two occurs is -
(ii) The minimum distance between the two is –
(i) The time at which minimum distance between the two occurs is -
(ii) The minimum distance between the two is –
Question 3
A particle starts from rest and moving along a straight line travels 19m in the tenth second. The acceleration of the particle is given by -
Question 4
Several particles are projected from a point in various direction but with same initial speed ‘vo’. At any subsequent time ‘t’.
Question 5
A person standing near the edge of the top of a building throws two balls A and B. The ball A is thrown vertically upwards and B is thrown vertically down with same speed. The ball A hits the ground with speed vA and ball B hits the ground with speed vB, then –
Question 6
Two balls are dropped from the top of a high tower with a time interval t0 second, where t0 is smaller than the time taken by the first ball to reach the floor, which is perfectly inelastic. The distance ‘s’ between the two balls, plotted against the time lapse ‘t’ from the instant of dropping the second ball is best represented by –
Question 7
A particle moves with constant speed v along a regular hexagon ABCDEF in the same order (i.e. A to B, B to C, C to D, D to E, E to F, F to A...). Then the magnitude of average velocity for its motion from A to C is -
Question 8
A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, followed again by 5 steps forward and 3 steps backward, and so on. Each step is 1 m long and required 1 second to cover. How long the drunkard takes to fall in a pit 13 m away from the start?
