JIPMER Physics Mock Test - 5 - Question 9

A wheel of radius R is rolling along a horizontal surface with a speed u. A pebble trapped on the wheel gets separated from the highest point of the wheel when the wheel arrives at position P (fig.). The horizontal range PQ of the pebble is

Detailed Solution for JIPMER Physics Mock Test - 5 - Question 9

Considering the vertical motion of the projectile (pebble), the time taken to reach the ground after leaving the wheel is given by
2R = 0 + 12 gt2, from which t = 2 ( Rg )
The horizontal range of the pebble is PQ = horizontal velocity x time of flight
The centre of mass of the wheel is moving with speed u.
The pebble at the topmost point of the wheel is moving horizontally with speed u with respect to the wheel so that the horizontal velocity of the pebble with respect to the ground is u + u = 2u.
Therefore, horizontal range PQ = 2u x 2 ( Rg ) = 4u √(R/g)

JIPMER Physics Mock Test - 5 - Question 28

A bullet moving with a speed of 100 ms-1 can just penetrate two planks of equal thickness. Then, the number of such planks penetrated by the same bullet when the speed is doubled, will be

Detailed Solution for JIPMER Physics Mock Test - 5 - Question 28

From equation of motion v2 = u2 + 2as
Let thickness of one plank is x, when bullet speed is 100 ms-1, then it is able to penetrate two planks.
Thus,
0 = 1002 + 2a x2x
⇒ 2a = -((100)2/2x)
Let it be able to penetrate n planks when bullet speed is doubled.
0 = (200)2 + 2a x nx
⇒ (200)2 = ((100)2/2x) x nx
⇒ (n/2) = 4
⇒ n = 8.
