Question

A scooter acquires a velocity of 36km/h in 10 s just after the start. It takes 20sec to stop. Calculate the acceleration in the 2 cases

Answer 1

1) 10/10= acceleration....36km/he= 10m/s
1m//s = acceleration
2)(0-10)/20= acceleration
-10/20= -0.5m/s= acceleration

Answer 2

s =36*5/18
v = 10m/s

a = v/t
= 10/10
= 1

a = v/t
a = 10/20
=0.5
