Tell me correct answer:​

Answer 1

Answer:

Its acceleration is 0.0185 m/s².

Explanation:

Given:

Speed (v) = 60 km/hr

Time (t) = 10 mins

To Find:

Acceleration = ?

Formula to be used:

${\red{\bf \longrightarrow Acceleration, \ a = \dfrac{v-u}{t}}}$

Where,

• u = Initial velocity
• v = final velocity
• t = time taken

Solution:

Before solving the question,

First, let's convert the units,

➡ Speed : 60 km/hr = 11.11 m/s.

➡ Time : 10 mins = 600 mins.

__________________________

$\longrightarrow \sf a = \dfrac{v-u}{t}$

$\longrightarrow \sf a = \dfrac{11.11 - 0}{t}$

$\longrightarrow \sf a = \dfrac{11.11}{600}$

$\longrightarrow \sf a = 0.0185 \ m/s^2$

$\therefore$ The acceleration is 0.0185 m/s².
