Answer:
4.617 s
Explanation:
The speed of 60 mi/h can be converted to m/s:
(60 mi/h) × (1609.344 m/mi) × (1 h)/(3600 s) = 26.8244 m/s
The relationship between speed and acceleration is ...
v = at
t = v/a = (26.8244 m/s)/(5.81 m/s²) ≈ 4.617 s
It will take the car 4.617 seconds to reach 60 mi/h starting from rest.
Only the speed will change because it is in motion
Answer:
The motion of particles in any object moves randomly I think
