Question

A bike start from ray and increasing it velocity by 10 m/sec in 5 second what is value of acceleration?​

Answer 1

Explanation:

Answer 2

Answer:

• Acceleration is 2 m/s².

Given:

• Final velocity = 10 m/s
• Time taken = 5 sec

Explanation:

$\rule{300}{1.5}$

Here, we are given that a bike starts from rest and attains a velocity of 10 m/s in 5 sec. We are asked to find it's acceleration.

Since, it starts from rest, so it's initial velocity will be zero.

From first kinematic equation we know,

$\longrightarrow{\sf{v\ =\ u\ +\ at}}$

Substitute the values,

$\longrightarrow{\sf{10\ =\ 0\ +\ a \times 5}} \\ \\ \\ \longrightarrow{\sf{10\ =\ 0\ +\ 5a}} \\ \\ \\ \longrightarrow{\sf{\dfrac{10}{5}\ =\ a}} \\ \\ \\ \longrightarrow{\sf{2\ =\ a}} \\ \\ \\ \longrightarrow{\sf{a\ =\ 2\ m/s^2}}$

∴ The acceleration of the bike is 2 m/s².

$\rule{300}{1.5}$
