How do we calculate velocity?

Suppose An Object In Free Fall Is Dropped From A Building. Its Starting Velocity Is 0 m/s. Ignoring The Effects Of Air Resistance, What Is The Speed (in m/s) Of The Object After Falling 3 Secs?

In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with charges measured in a fictitious unit called a zeet (Z). Drop Charge (Z) A) 1.77 * 10⁻¹⁴ B) 4.13 * 10⁻¹⁴ C) 4.72 * 10⁻¹⁴ D) 5.

Now that we know the velocity of the cart before the collision is 1.80m/s, let's use this to determine the linear momentum and kinetic energy of the disk-cart system before the collision. The mass of the cart is 23.5kg. The mass of the disk is 11.

A circuit is built based on the circuit diagram shown. A diagram of a closed circuit with a power source on the left labeled 60 V. There are 3 resistors in parallel, separate paths, connected to it labeled 40 Ohms, 50 Ohms and 30 Ohms.

After harvesting their main crops, such as corn and wheat, many farmers plant a second crop called a cover crop. This cover crop grows during the fall and winter and is then plowed over in the spring. What is the main purpose of a cover crop? A.
