Question

A van accelerates uniformly & its velocity changes from 5m/s to 25m/s in time t.find its average velocity

Answer 1

Acceleration = Rate of change of velocity = Difference in velocities in m/s divided by time in seconds

Acceleration = (25 - 5) m/s / 4 s = 5 m/s2

Answer 2

if there is any acceleration given then you can put the first equation b is equal to you + 80 then you can find out tea and when you can be used you can subtract final velocity from initial velocity divided by time change in time that is 25 m per second - 5 M per second upon final time / initial time
HOPE IT HELPS YOU
CHEERS !!
