Question

using the formula v=u+at to find the velocity
initial velocity is 3m/s
acceleration is 1.5m/s
time is 7 seconds

Answer 1

Answer:

Step-by-step explanation:

V=u+at

V=3+1.5×7

V=3+10.5

V=13.5 m/s

Answer 2

Given - initial velocity is 3m/s

acceleration is 1.5m/s

time is 7 seconds

formula v=u+at

Find - Velocity from given formula

Solution - In the given formula, v stands for final velocity, u stands for initial velocity, a stands for accelaration of the body and t refers to time taken.

Now, since all the values are in same units, they can be directly kept in the formula to find final velocity.

v = 3 + (1.5*7)

v = 3 + 10.5

v = 13.5 metres

Thus, final velocity obtained from the formula is 13.5 metres.
