Question

a wooden slab starting from rest slides down an inclined plane of length 10m with an acceleration of 5m/s.. what would be its speed at the bottom of the inclined plane?

Answer 1

Wooden slab starts sliding down from rest

So the initial velocity u=0

The length of the inclined plane is 10 m 

So s=10

Its acceleration is 5m/s²

So a=5m/s²

We need to find the final velocity i.e v

Using the equations of motion

v²-u²=2as

v²-0²=2*5*10

v²=100

v=√100

So v is 10

The final velocity of the Wooden slab is 10m/s
