Question

an object is slide 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

Answer 1

Howdy!!

your answer is ----

Given, initial velocity u = 10cm/s

& final velocity v = 15cm/s
and time period t = 2sec

therefore ,

acceleration a = v-u/t

=> a = 15-10/2 = 5/2

=> a = 2.5cm/s^2

hope it help you

Answer 2

Answer:

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

Final velocity = 15 m/s = 0.15 m/s

Time taken = 2 seconds

Acceleration = final velocity – initial velocity/ time taken  

= 0.15 – 0.1/ 2

= 0.05/ 2

= 0.025 m/s
