Question

Consider a car moving on a straight road with a speed of 100ms- 1 . The distance at which car can be stopped is ((μ )k = 0 .5) (A) 400m (B) 100m (C) 1000m (D) 800m

u=100ms- 1, v=0, a=-μ g Using v2 - u2 = 2 a S , 02-100× 100=-2× 0.5× 10× S or S=(100 × 100/10)m=1000m

Q. Consider a car moving on a straight road with a speed of $100 m s^{- 1}$ . The distance at which car can be stopped is $((μ)_{k} = 0.5)$

$400 m$

$100 m$

$1000 m$

$800 m$

$u = 100 m s^{- 1}, v = 0, a = - μg$
Using $v^{2} - u^{2} = 2 a S,$
$0^{2} - 100 \times 100 = - 2 \times 0.5 \times 10 \times S$
or $S = \frac{100 \times 100}{10} m = 1000 m$

Q. Consider a car moving on a straight road with a speed of 100ms−1 . The distance at which car can be stopped is ((μ)k​=0.5)

400m

100m

1000m

800m
