Answer:
13.5m/s^2
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
Use formula v=u +at to find the velocity when the initial velocity is 3m/s, the acceleration is 1.5m/s2 at t= 7s
The given formula is
v=u +at
a= 1.5m/s2
t= 7s
initial velocity = u= 3m/s,
Final velocity= v=?
From the given eqn we can substitute our values to get final velocity
v=u +at
v= 3+(1.5×7)
= 3+10.5
=13.5m/s^2
Hence, the final velocity=13.5m/s^2
