Answer :
Answer:
Final velocity, V = 35.5m/s
Explanation:
Given the following data;
Initial velocity = 28m/s
Acceleration = 2.5m/s²
Time = 3 seconds
To find the final velocity, we would use the first equation of motion
V = U + at
Where;
V is the final velocity measured in m/s.
U is the initial velocity measured in m/s.
a is the acceleration measured in m/s².
t is the time measured in seconds.
Substituting into the equation, we have;
V = 28 + 2.5*3
V = 28 + 7.5
Final velocity, V = 35.5m/s
