Question

A truck travelling at 25 m/s puts its brakes on for 4 s. This produces a retardation of 2 m/s squared. What does the truck's velocity drop to ?

Answer 1

PLZ MARK MY SOLUTION AS THE BRAINLIEST.
WE KNOW THAT,
v = u + at
v = 25 - (2 × 4)
v = 25 - 8 = 17
SO, FINAL VELOCITY IS 17 m/s

Answer 2

u=25 m/s;t=4s;a=_2m/s^2  then v=u+at =25+(_2)×4 =17m/s
