Question

The initial velocity of a micro van is 15 m/s. It gains a velocity of 40 m/s
in 10 seconds. Calculate the average velocity and acceleration of the
van. please fast ​

Answer 1

Answer:

Acceleration= 2.5m/s^2

Average velocity=27.5 m/s

Step-by-step explanation:

Initial velocity= 15 m/s

Final velocity= 40m/s

Time= 10s

Acceleration

=(v-u) /t

= (40-15)/10 m/s^2

=2.5m/s^2

Average velocity

=( ut+1/2at^2) /t

= (15×10+1/2×2.5×100)/10 m/s

=275/10 m/s

= 27.5 m/s

OR

Average velocity

= (v+u) /2

= (40+15/2 m/s

= 55/2 m/s

=27.5 m/s
