Question

a bus starting from rest moves with a uniform acceleration 2ms-² for 1 minute
find
a- the speed acquired
b- the distance travelled​

Answer 1

Answer: The bus starts from rest, therefore:

initial velocity (u) =  0 m/s

acceleration = 2 m/s²

time = 2 minutes = 120 seconds

a) final velocity = initial velocity + (acceleration * time)

  v = 0 + 2 x 120

  v = 240 m/s

b) distance = ut + 1 / 2 x at²

   s = 0 + 1 / 2 x 2 x (120)²

   s = 14400 m = 14.4 km
