A. A ball is thrown directly up with an initial speed of 4.00 m/s at y = 0. What is the maximum height hth that it achieves, and what time did that take? Show the final formulas for the quantities, along with the numerical answers. At 30 fps how many frames would be recorded in a video of the throw? At 120 fps?
B. From the height h in slide 2 the ball then drops back to y = 0. Find the time t0 that takes, and the velocity there (magnitude and direction). Show the final formulas for the quantities, along with the numerical answers.
C. Find the two times the ball is at the height y = ½ h. Show the final formula and the numerical answers.
D. Roughly sketch on a piece of paper what you expect the plots of y versus t and vy versus t will look like, take a picture, and paste them here.
we dont really use our textbooks book that much but we haveproblems like what is the differnce between temperature and heat
A certain amount of oxygen gas occupies a volume of 12 liters when its temperature is 20 oC and its pressure is 1 atm. Calculate the number of grams of oxygen:
find the charge on the block. A very small charged block with a mass of 2.05g is placed on an insulated, frictionless plane inclined at an angle of 17° with respect to the horizontal.
An electron going east with speed ve = 0.4c collides with a proton going north with speed vp = 0.3c. This collision will create a photon. Find the direction of the photon
A wire is formed into a circle having a diameter of 10.3 cm and is placed in a uniform magnetic field of 2.84 mT. Find the maximum torque on the wire
A model car is propelled by a cylinder of carbon dioxide gas. The cylinder emits gas at a speed of 4.5 g/s with an exit speed of 80.0 m/s. The car has a mass of 400 g, including the CO2 cylinder. Starting from rest, what is the car's initial accel..

A 45.0-Ω resistor, a 0.100-H inductor, and a 10.0-muF capacitor are connected in series to a 60.0-Hz source. The rms current in the circuit is 2.25 A. Find the rms voltages across the resistor.
A 2.2-kg cart is rolling along a frictionless, horizontal track towards a 1.9-kg cart that is held initially at rest. What was the velocity of the first cart when the second cart was still at rest
A man stands on the roof of a building of height 16.8m and throws a rock with a velocity of magnitude 31.8m/s, Calculate the magnitude of the velocity of the rock just before it strikes the ground
A rocket-powered hockey puck has a thrust of 2.5 N and a total mass of 1.0 kg. It is released from rest on a frictionless table, 5.5 m from the edge of a 2.0 m drop. The front of the rocket is pointed directly toward the edge. How far does the puck l..
