You dive straight down into a pool of water. You hit the water with a speed of 5.0 m/s , and your mass is 70 kg.

Assuming a drag force of the form FDFD = (−1.50×10⁴ kg/s )v, how long does it take you to reach 2% of your original speed? (Ignore any effects of buoyancy.)

A white billiard ball with mass m_w = 1.33 kg is moving directly to the right with a speed of v = 2.96 m/s and collides elastically with a black billiard ball with the same mass m_b = 1.33 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of ?_w = 29

An undisturbed core of soil at field capacity was taken from a field site had a wet weight of 420 g. The following information was measured in the lab. The oven dry wt of the soil = 345 g Bulk Density = 1.15 g/cm3 What is the moisture content of the soil on a volume basis (volumetric water content Theta v)

A gas expands from point A to B. The expansion consists of two stages.

Stage 1) The gas expands at constant pressure from 15 to 39 litres.

Stage 2) The gas expands from 31 litres to 82 litres with a pressure drop according to the equation; P = 100 - 0.8 V kPa

Calculate the work done on the gas.

Let T be a graph. Suppose there is a unique path between every pair of vertices in T. Prove that T is a tree.

Can I do this using the contraposative? Like Let u,v be in T and since I am assuming T to not be a tree this allows cycles to occur thus the paths must not be unique. Am I on the right track?

Two stationary positive point charges, charge 1 of magnitude 3.20nC and charge 2 of magnitude 2.00nC , are separated by a distance of 42.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed v-final of the electron when it is 10.0cm from charge 1?
