Answer:
17 m/s
Explanation:
As per the provided information in the given question, we have :
Initial velocity (u) = 7.0 or 7 m/s
Acceleration (a) = 2.0 or 2 m/s²
Time taken (t) = 5 seconds
We are asked to calculate its velocity at the end of 5 seconds i.e, its final velocity.
By using the first equation of motion,
⇒ v = u + at
v denotes final velocity
u denotes initial velocity
a denotes acceleration
t denotes time
⇒ v = 7 + 2(5)
⇒ v = 7 + 10
⇒ v = 17 m/s
∴ Its velocity at the end of 5 seconds is 17 m/s
