Question

A body starts from rest acquires a velocity 540 m s-in 0.05 h. find the acceleration. ​

Answer 1

Answer:

3 m/s²

Explanation:

initial velocity (u) = 0 m/s

final velocity(v) = 540 m/s

time taken(t) = 0.05 hours = 0.05 × 3600 = 180 seconds

acceleration = (v-u)/t = (540-0)/180 = 540/180 = 3 m/s²

Answer 2

ProvidEd that:

• Initial velocity = 0 m/s
• Final velocity = 540 m/s
• Time = 0.05 hr

To calculaTe:

• The acceleration

SolutioN:

• The acceleration = 3 m/s sq.

UsiNg concepts:

• Acceleration formula
• Formula to convert hr-sec

UsiNg formulas:

• a = (v-u)/t
• 1 hr = 3600 seconds

RequirEd solution:

~ Converting hour into seconds!

▶️ 1 hr = 3600 s

▶️ 0.05 = 0.05 × 3600 seconds

▶️ 0.05 hr = 180 seconds

~ Finding acceleration!

▶️ a = (v-u)/t

▶️ a = (540-0)/180

▶️ a = 540/180

▶️ a = 54/18

▶️ a = 3 m/s sq.

▶️ Acceleration = 3 m/s sq. $\:$
