Determine the mechanical energy of this object: a 2-kg pendulum has a speed of 1 m/s at a height of 1/2 meter.

a: 1 j
b: 10.8 j
c: 2 j
d: 9.8 j

The mechanical energy of this object is 10.8 Joules.

Explanation:

Mechanical energy is the sum of kinetic energy and potential energy.

m = mass of the object

v = velocity of the moving object

h = height at which an object is placed

g = Acceleration due to gravity

We have : m = 2 kg. v = 1 m/s , h = 1/2 m

The mechanical energy of this object is 10.8 Joules.

the force required to move the cart is divided by three or 33.33 n.
