JEE MATHEMATICS MCQ: RATE MEASURE

1 Easy

1 of 1

Application +4 | -1

A lizard, at an initial distance of

21 \mathrm{~cm}

behind an insect, moves from rest with an acceleration of

2 \mathrm{~cm} / \mathrm{s}^2

and pursues the insect which is crawling uniformly along a straight line at a speed of

20 \mathrm{~cm} / \mathrm{s}

. Then the lizard will catch the insect after

View answer and explanation

Correct option: C

21 \mathrm{~s}

Option C (

21 \text{{ s}}

) is correct because the time it takes for the lizard to catch the insect is calculated to be 21 seconds.

4500 \pi

cubic meters of helium gas. If a leak in the balloon causes the gas to escape at the rate of

72 \pi

cubic meters per minute, then the rate (in meters per minute) at which the radius of the balloon decreases 49 minutes after the leakage began is: A solid box is formed by placing a cylinder, having equal height and radius on top of a cube such that, the circular base of cylinder is the inscribed circle for square top of the cube. If the radius of cylinder is changing at the rate
