Question

A bus starting from rest moves with a uniform acceleration of 0.2ms-2 for three minutes . Find the velocity acquired

Answer 1

By using the first equation of motion,(v=u +at)
V=36m/s

Answer 2

Do you know 3 equation of motion.
U van solve it easily.
Okay first acceleration= change in velocity per unit time.
Or, (v-u)/t =a
Or, v= u+at
Or, v=0+0.2ms-2 ×( 3×60)s (1 min= 60s)
Or, v= 0+0.2ms-2 ×180s
Or, v=0+36m/s (m/s^2 × s= m/s)
Or v =36 m/s
