# A kg wood block is launched up a wooden ramp that is inclined at a angle. The block’s initial speed is m/s. a. What vertical height does the block reach above its starting point? b. What speed does it have when it slides back down to its starting point?

a). Vertical height the block reach above it starting point is m

b). Speed it slides back down to its starting point m/s

See the step by step solution

## Step 1. Given Information

The weight of wood block is kg

Inclined angle of ramp

Initial speed is m/s

## Step 2. Part a). Finding the vertical height

The coefficient of kinetic friction between two wood is

m/s and the

m/s we can solve for acceleration.

Solving for summation of forces horizontally with respect to the wooden ramp that is inclined for

is the distance traveled by the block

## Step 3. Part b). Finding the vertical height

Compute the acceleration going down the ramp

Let's calculate the final velocity when it slides back down
