Question

if you answer this question correctly I will follow you I will mark the brain liest and I will thank you and the correct answer was 0.42 M per second square ####I want by step

Answer 1

here you go ☆☆
given:-
u=60km/h
16.7m/s

v=45km/h
12.5m/s
t=10s

a=?


using equation of motion:-
v=u+at

12.5=16.7+a×10
12.5 - 16.7 = 10a
-4.2=10a

a=-4.2×10

a=-42ms^2


hope it helps you......
