An elevator (lift) ascends with an upward acceleration of 1.2 `ms^(-2)`.At the instant when its upward speed is 2.4 `ms^(-1)`, a loose bolt drops from the ceiling of the elevator 2.7 m above the floor of the elevator . Calculate (a) the time of flight of the bolt from the ceiling to the floor and (b)the distance it has fallen relative to the elevator shaft.

An elevator (lift) ascends with an upward acceleration of 1.2ms^-2 . At the instant when its upward speed is 2.4 ms^-1 , a loose bolt drops from the ceiling of the elevator 2.7m above the floor of the elevator. Calculate (a) the time of flight of the bolt from the ceiling to the floor and (b) the distance it has fallen relaative to the elevator shaft.

An elevator of height 'h' ascends with constant acceleration 'a' . When it corsses a plalform bolt drops from the top of the elevator. If the time for the bolt to hit the floor of the elevator is sqrt((lambdah)/(g + a)) then find 'lambda' .

An elecator is going up with an upward acceleration of 1m//s^2 . At the instant when its velocity is 2 m//s , a stone is projected upward from its floor with a speed of 2m//s relative to the elevator, at an elevation of 30^@ . (a) Calculate the time taken by the stone to return to the floor. (b) Sketch the path of the projectile as observed by an observer outside the elevator. (c) If the elevator was moving with a downward acceleration equal to g, how would the motion be altered?

An elevator car (lift) is moving upward with uniform acceleration of 2 m//s^(2) . At the instant, when its velocity is 2 m/s upwards a ball thrown upward from its floor. The ball strikes back the floor 2s after its projection. Find the velocity of projection of the ball relative to the lift.

A very broad elevator is going up vertically with constant acceleration of 2 m/s^(2) . At the instant when its velocity is 4 m/s a ball is projected from the floor of the lift with a speed of 4 m/s relative to the floor at an elevation of 30^(@) . The range of ball over the floor of the lift is :

An elevator is accelerating downwards with an acceleration of 4.9 ms ""^(-2) . A barometer placed in this elevator reads 75 cm of Hg. Calculate the air pressure inside the elevator.

A very broad elevator is going up vertically with a constant acceleration of 2m//s^(2) . At the instant when its velocity is 4m//s , a ball is projected from the floor of the lift wht as of 4m//s relative to the floor at an elevation of 30^(@) . The time taken by the ball to return the floor is (g=10m//s^(2))

A lift starts ascending with an acceleration of 4 ft//s^(2) . At the same time a bolt falls from its cieling 6ft above the floor. Find the time taken by it to reach the floor. g= 32 ft//s^(2)

An elecator in which a man is standing is moving upwards with a speed of 10ms^(-1) if the man drops a coin from a height of 2.45 m from the floor of elevator it reaches the floor of the elevator after time (g=9.8ms^(-2))

An elevator is accelerating upwards with a constant acceleration a ms^-2 . If a coin is dropped in it by a passenger, then.
