A cart is sliding on a smooth incline An observer `(O_(1))` is fixed to cart and another abserver fixed on ground `(O_(2))` observes a loose bolt that is released from ceiling at the instant of release cart has velocity `v_(0)` as seen by `O_(2)` Mark the correct option

A

Trajectory of bolt for `O_(1)` is parabola

B

Trajectory of bolt for `O_(2)` is straight line inclined at an angle 0with verticle

C

Trajectory of bolt for `O_(2)` is a straight line perpendicular to ceiling of cart.

D

Trajectory of bolt for `O_(1)` is straight line

Text Solution

Verified by Experts

The correct Answer is:
D

for observer on cart
` vec(v)_(rel)=0`
` vec(s) _(rel)=1/2vec(a)_(rel)t^(2)`
Trajectory is straight line along `vec(a)_(rel)` for observer on ground trajectory is parabola because `vec(v) _(0)and vec(g)` are at angle `theta` initially

(i) In a car race sound signals emitted by the two cars are detected by the detector on the straight track at the end point of the race. Frequency observed is 330 Hz and 360 Hz. The original frequency of horn is 300 Hz for both cars. Race ends with the separation of 1000 m between the cars. Assume both cars move with constant velocity and velocity of sound is 330 m/s. Find the time (in seconds) taken by the winning car to finish the race. (ii) A source of sound of frequency f is dropped from rest from a height h above the ground. An observer O_(1) is located on the ground and another observer O_(2) is inside water at a depth d from the ground. Both O_(1) and O_(2) are vertically below the source. The velocity of sound in water is 4V and that in air is V. Find (a) The frequency of the sound detected by O_(1) and O_(2) corresponding to the sound emitted the source initially. (b) The frequency detected by both O_(1) and O_(2) corresponding to the sound emitted by the source at height h//2 from the ground.
