Question

An object moving north with an initial velocity of 14 m/s accelerates 5 m/s^2 for 20 seconds.what is the final velocity of the object?

39 m/s
90 m/s
114 m/s
414m/s

Answer 1

The answer is 114 m/s good luck!!!

Answer 2

Option C = 114 m/s

Step-by-step explanation:

a=v-u/t

By substituting,

5=v-14/20

100=v-14

Thus, v=100+14

v= 114 m/s

Hope it helps :)
