Answer:
Explanation:
Required
The units of A and B
From the question, we understand that:
This implies that each of 
and 
will have the same unit as 
So, we have:
The unit of t is (s); So, the expression becomes
Divide both sides by 
Answer:
a = -4/5 m/s^2
Explanation:
Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
a = (20 m/s - 60 m/s) / 50 s
a = -40 m/s / 50 s
a = -4/5 m/s^2
