Question

A car traveling at 22.4 m/s skids to a stop in 2.55 s. Determine the skidding distance of the car (assume uniform acceleration)

Answer 1

here is your ans

u = 22.4m

t = 2.55

v = 0

now , we have to find acceleration :-

by :- v = u +at

0 = 22.4 + a2.55

a = -8.78so,

by :- s = ut+1/2at²

s = 43.93 m ans.
