A particle starts from rest and travel with uniform velocity of 50 cm per second. how far will it go in 4 minutes​

Answer 1

• initial velocity=0m/s
• Final velocity=v=50m/s
• Time=t=4min=240s
• Acceleration=?

We know

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \sf\longmapsto Acceleration=\dfrac{50-0}{240}$

$\\ \sf\longmapsto Acceleration=\dfrac{50}{240}$

$\\ \sf\longmapsto Acceleration=0.2m/s^2$

We know.

$\boxed{\sf s=ut+\dfrac{1}{2}at^2}$

$\\ \sf\longmapsto s=0(240)+\dfrac{1}{2}\times 0.2\times 240^2$

$\\ \sf\longmapsto s=0.2\times 14400$

$\\ \sf\longmapsto s=2880m$
