JEE · NEET Previous Year Question

$Consider a car moving on a straight road with a speed of 100 m/s. The distance at which car can be stopped is [µ_{k} = 0.5]$

Topic: JEE PYQ

Answer: D. Full step-by-step solution below.

A $100 m$
B $400 m$
C $800 m$
D $1000 m$

Correct answer: D

Solution

(d) s = \frac{v ^{2}}{2 μ _{k} g} = \frac{100 \times 100}{2 \times 0.5 \times 10} = \frac{100 \times 100}{5 \times 2} = 1000 m
