Question

A bus starts from the bus depot, moves with an acceleration of 0.5m/s2 for 2 minutes. Find the speed acquired.​

Answer 1

GIVEN :–

• Acceleration (a) = 0.5 m/s²

• Time (t) = 2 minute = 2 × 60 sec = 120 sec

• Initial velocity (u) = 0 m/sec

TO FIND :–

• Acquired speed (v) = ?

SOLUTION :–

• We know that –

☞ v = u + at

• Now put the values –

⇒ v = (0) + (0.5)(120)

⇒ v = 0 + (120)/(2)

⇒ v = 60 m/sec

Answer 2

Answer:60ms⁻¹

Explanation:

acceleration due to gravity(a)=0.5ms⁻²

time (t)=2 minutes=2(60) seconds

initial velocity(u)= 0ms⁻¹

final velocity(v) = ?

a=v-u/t

v=u +a t

v=0ms⁻¹ +(0.5ms⁻²) ×120 s

v= 60 ms⁻¹
