1 answer:
The force of friction is 19.1 N
Explanation:
According to Newton's second law, the net force acting on the bag is equal to the product between its mass and its acceleration:
where
is the net force
m is the mass
a is the acceleration
The bag is moving at constant speed, so its acceleration is zero:
Therefore the net force is zero as well:
Here we are interested only in the forces acting along the horizontal direction, therefore the net force is given by:
where
is the horizontal component of the applied force, with
F = 22.5 N
is the force of friction
And solving for , we find

The height, h to which the package of mass m bounces to depends on its initial velocity, v and the acceleration due to gravity, g and is given below:
Perfectly elastic collisions are collisions in which the momentum as well as the energy of the colliding bodies is conserved.
In perfectly elastic collisions, the sum of momentum before collision is equal to the momentum after collision.
Also, the sum of kinetic energy before collision is equal to the sum of kinetic energy after collision.
Since some of the Kinetic energy is converted to potential energy of the body;
Therefore, the height to which the package m bounces to depends on its initial velocity and the acceleration due to gravity.
