Answer:
1. Questions:
A. 10 km/h
B. 60 km/h
C. 5 seconds
D. 10 km/h
Given Data:
A. 10 km/h
B. 60 km/h
C. 5 seconds
Required: 10 km/h²
Explination:
To find acceleration, this is the formula
vf stands for final velocity
vi stands for initial velocity
t stands for time
a stands for acceleration
A= vf-vi ÷ t
A= 60-10 ÷ 5
A= 50 ÷ 5
A= 10km/h²
Hope it helps:))
