Question

a car travelling at 36 km/hr due north turns west in 5 s under constant acceleration and maintains the same speed. the acceleration of the car is

Answer 1

If acceleration is constant we calculate it from the formula:
a=
`(v)/(t)`
v=36
`(km)/(h)`
t=5s
We convert units:
t=5s=
`(1)/(12)`h
a=
`(36)/( (1)/(12))`=432
`(km)/(h²)`=0,033333333333333
`(m)/( s^(2) )`
