Answer:
Here,
Initial velocity (u) = 10m/s
Acceleration (a) = 2.5m/s sq.
= 25/10 m/s sq.
Time (t) = 10 seconds
Final velocity (v) = ?
We know, from the 1st eq. of motion,
v = u + at
Therefore, v = 10 + ( 25/10 × 10)
v = 10 + 25
v = 35 m/s
Note: The square should be written on top of the digits and not to be written as sq. . I have written sq. for my convenience.
Hope this helps you.
