Answer:
modern vehicles are made to crunch up a little bit so they that absorbe some of the impact instead of you
Explanation:
Answer:
a)Δs = 834 mm
b)V=1122 mm/s

Explanation:
Given that

a)
When t= 2 s


s= 114 mm
At t= 4 s


s= 948 mm
So the displacement between 2 s to 4 s
Δs = 948 - 114 mm
Δs = 834 mm
b)
We know that velocity V


At t= 5 s


V=1122 mm/s
We know that acceleration a


a= 90 t
a = 90 x 5

Answer:
current is measured in Ampere (A)
