The document discusses work problems involving boxes being pushed and carts accelerating. It asks the reader to calculate the work done by moving a 7kg box 13m that then fell 350m, and to find the work done by a cart that displaced 17m while accelerating at 2 m/s^2 with a mass of 12kg. It also provides brief definitions of energy as the ability to do work by exerting a force over a displacement, and kinetic energy as the energy an object has due to its motion which requires work to accelerate it by applying a force.
2. 4. A box with a mass of 7kg is being pushed by the force 15N
and traveled 13m from the initial place of the box to the edge of
the cliff , but the box fell from the cliff with a height of 350m to
reach the ground.
A. Find work done by the box at the top of the cliff.
B. The work done from edge to the ground.
C. Total work done by the box.
3.
4. 5. The cart displaced 17m by the mass equal to 12kg and
accelerate 2 m/s^2 horizontally. Find the work done by the
cart.
5. ENERGY
Ability to do work, which is the ability to exert a
force causing displacement of an object.”
6. KINETIC ENERGY
The energy an object has because of its
motion. If we want to accelerate an object,
then we must apply a force. Applying a force
requires us to do work.
