Aforce of 92.0n is exerted straight up on a small troll that weighs 73.5n. find the acceleration of the troll.

Explanation:

We have the following data:

is the force exerted on the troll

is the weight of the troll

Now, the weight is expressed as:

(1)

Where is the mass of the troll and is the acceleration due gravity

Isolating :

(2)

(3)

(4) This is the mass of th troll

On the other hand, the exerted force is given by:

(5)

Where is the acceleration:

(6)

(7)

Finally:

This is the acceleration of the troll

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
