Question

A bicycle starting from rest picks up a velocity of 5m/s over a time period of 100s. Find the
acceleration of the bicycle.​

Answer 1

Given

A bicycle starting from rest picks up a velocity of 5m/s over a time period of 100s.

To find

Find the acceleration of the bicycle.

Solution

• Initial velocity (u) = 0
• Final velocity (v) = 5m/s
• Time taken (t) = 100s
• Acceleration (a) = ?

*According to first equation of motion*

→ v = u + at

→ 5 = 0 + a*100

→ 5 = 100a

→ a = 5/100 = 0.05m/s²

Hence, the acceleration of bicycle is 0.05m/s²

Answer 2

Answer:

Explanation:

Given :-

Initial velocity of bicycle, u = 0 (As starts from rest)

Final velocity of bicycle, v = 5 m/s

Time taken, t = 100 seconds

To Find :-

Acceleration, a = ??

Formula to be used :-

1st equation of motion

i.e, v = u + at

Solution :-

Putting all the values, we get

v = u + at

⇒ 5 = 0 + a × 100

⇒ 5 = 100a

⇒ 5/100 = a

⇒ a = 0.05 m/s²

Hence, the  acceleration of the bicycle is 0.05 m/s².
