calculate the total mechanical energy of a pendulum as it swings from its highest point to its lowest point pendulum mass is 4kg use your equations for gravitational potential energy and kinetic energy to determine these values based on the data given below total energy is the sum of gravitational potential energy and kinetic energy in this problem round gravity to G=10 m/s^2

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
