Question

If u= 3m/s; a = 5 m/s and t = 4 sec, calculate v *
23 m/s
180 m/s
19 m/s
60 m/s​

Answer 1

Answer:

acceleration = change in velocity / time =v-u/t

gives is

acceleration (a)=5m/s

final velocity (v)= ?

initial velocity (u)=3m/s

time (t)=4sec

5=v-3/4

5x4=v-3

20=v-3

20+3=v

23m/sec
