Question

A car moving along a craight highway with a velocity of
20m/s brought to a stop with a distance of loom, what is the
Retardation
of the ear and how
long
does it take
for car
to stop?​

Answer 1

Answer:

⇒ u = 126 km / h = 126 × 5 / 18 m / s = 35 m / s

⇒ v = 0⇒ s = 200 mNewton's Equation of motion

⇒ v ² - u ² = 2 as

⇒ 0 ² - 35 ² = 2a ( 200 )

⇒ a = - 3.0625 m / s ²

⇒ v = u + at⇒ 0 = 35 - 3.06 t

⇒ t = 11.4 s
