1. A bus starting from rest moves
with a uniform acceleration of
0.1 m s2 for 2 minutes. Find (a)
the speed acquired. (b) the
distance travelled.​

Respuesta :

Answer:

Speed acquired (Final velocity) = 12 m/s

Distance travelled = 720 meter

Explanation:

Given:

Uniform acceleration = 0.1 m/s²

Initial velocity = 0 m/s

Time taken = 2 minutes = 2 x 60 = 120 second

Find:

(a)  Speed acquired (Final velocity)

(b) Distance travelled

Computation:

v = u + at

v = 0 + 0.1(120)

Speed acquired (Final velocity) = 12 m/s

Distance travelled = ut + (1/2)(a)(t²)

Distance travelled = (0)(120) + (1/2)(0.1)(120²)

Distance travelled = (1/2)(0.1)(14400)

Distance travelled = 720 meter
