Question

. The final speed v of a car is given by the formula v=u + at.
[u initial speed, a= acceleration, t =
acceleration, t = time taken)
Find v when u = 15 m/s, a = 0.2 m/s?, 1 = 30 s.​

Answer 1

Answer:

v = 21 m/s

Step-by-step explanation:

Given: U= 15m/s. a= 0.2m/s². t=30s.____________ [1]

to find: v.

Formula: v=u+at.___________ [2]

by substituting values of [1] in [2]:

v= 15 + 0.2 × 30.

= 15 + 6

v= 21m/s.
