Compute all parts of given question:
Question: A baseball is thrown from the roof of a 22.0m tall building with an initial velocity of magnitude 12.0 m/sec and directed at an angle of 53.1 degrees above the horizontal.
Part A: What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance.
Part B: What is the answer for part (a) if the initial velocity is at an angle of 53.1 degrees below the horizontal?
Part C: If the effects of air resistance are included, will part (a) or (b) give the higher speed?
Show all work, use additional paper if necessary for above question.
Ammonia The ammonia molecule NH3 has apermanent electric dipole moment equal to 1.47 D, where 1 D = 1debye unit = 3.34 multiplied by 10-30 C·m. Calculate the electric potential due to an ammonia molecule at a point56.0 nm away along the axis of the d..
What is the flux of Zn moving down the rod? Write down all your assumptions (hint: you will need to look up the density of copper. You do not need to account for the variation in density with alloy composition). Clarify what the boundary conditions w..
Carbon dioxide gas (CO2) enters a pipe at a pressure of 3.5 MPa and a temperature of 450 K at a mass flow rate of 2 kg/sec. This gas flow is cooled at a constant pressure until its temperature drops to 400 K at the exit of the pipe.
The sketch at the left shows a square loop of wire. Its resistance is 5 ohm. Its dimensions are shown: a = 4.0 cm, b = 5.0 cm. The nearby wire carries a current of 10.0 A. What is the magnitude of the magnetic flux in the loop of wire?
A certain lightbulb has a tungsten filament with a resistance of 19.5 ? when at 20.0°C and 142 ? when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here. Find the temperature o..
A man enters a tall tower, needing to know its height. Henotes that a long pendulum extends from the ceiling almost to thefloor and that its period is 25.0 s. How tall is the tower
a sled is moving down an incline plane, the mass of the sled is 40 kg. the angle is 35 degrees, coefficient of kinetic friction is 0.3. Find acceleration of the sled
