Hey,
Who plays a role in the financial activities of a company?
<em>O D. Everyone at the company, including managers and employees</em>
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:
Magnitude of velocity=10.67 m/s
Magnitude of acceleration=24.62 ft/
