Question

ou have a cylinder. you don't know what its internal structure looks like, but you plan to roll it down a ramp, as in this week's procedure. the ramp is 1 m long, and is elevated at an angle of 15o. the mass of the cylinder is 450 g and its diameter is 2.1 cm. answer the following questions regarding this situation. question at position 3 3 0.2 points question at position 3 you set the cylinder and hold it at rest at the top of the ramp. how much total energy (in j) does the block have at the top of the ramp?

Answer 1

The total energy of the cylinder at the top of the ramp is 4.41 J.

Step-by-step explanation:

The total energy of the cylinder at the top of the ramp can be determined by considering its potential energy and kinetic energy.

1. The potential energy of the cylinder is given by the formula PE = mgh, where m is the mass of the cylinder (450 g), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the ramp (1 m). Thus, PE = 0.450 kg * 9.8 m/s^2 * 1 m = 4.41 J.
2. Since the cylinder is at rest at the top of the ramp, its initial kinetic energy is zero (KE = 0).

Therefore, the total energy of the cylinder at the top of the ramp is the sum of its potential energy and kinetic energy: 4.41 J + 0 J = 4.41 J.
