Question

An object is sliding down an inclined plane. The velocity changes at a constant rate from 10 cm/s to 15 cm/s in two seconds. What is its acceleration in metre per second square? 1 point Captionless Image (a) 0.1 (b) 0.029 (c) 0.025 (d) 0.40

${\red\bigstar\large\bold{\mathrm{\underline{\green{Given:}}}}}$

❥ Initial velocity = 10 cm/s = 0.1 m/s

❥ Final Velocity = 15 cm/s = 0.15 m/s

❥ Time Taken = 2 seconds

${\red\bigstar\large\bold{\mathrm{\underline{\green{To\:Find:}}}}}$

❥ Acceleration

${\red\bigstar\large\bold{\mathrm{\underline{\green{Solution:}}}}}$

$\bold{\pink{\boxed{\boxed{\sf{\orange{Acceleration\:=\: \dfrac{Final\:Velocity\:-\:Initial\:Velocity}{Time\:taken}}}}}}}$

$\star\sf Acceleration\:=\: \dfrac{0.15-0.1}{2}$

$\star\sf Acceleration\:=\: \dfrac{0.15-0.1}{2}$

$\star\sf Acceleration\:=\: \dfrac{0.05}{2}$

${\red\bigstar\large\bold{\mathrm{\underline{\green{Acceleration\:=\:0.025\:{m}^{2}}}}}}$
