Solve the all parts of given question:
Question: A cannon on level ground is aimed at 60 degrees above the horizon and fires a shell with a velocity of 300 m/s.
Part A: How far downrange does the shell hit?
Part B: Show that this range is the same if the cannon were aimed at 30 degrees?
Part C: For what angle is the time of flight greater?
I need help to determine for what angle is the time of flight greater.
what are the main parameters of voltage source and their physical meaning . how can we determine the voltage source
A 50 kg projectile is fired over level land at an angle of 30 degrees above the horizontal with a muzzle velocity of 210 m/s. At the highest point in its trajectory it explodes into two fragments, one of twice as much mass as the other. The less m..
A 66.0 kg person throwsa 0.0400 kg snowball forwardwith a ground speed of 32.0 m/s. A second person, with a massof 59.0 kg, catches thesnowball. Both people are on skates. The first person is initiallymoving forward with a speed of2.00 m/s, and th..
A bar magnet is oriented with its magnetic dipole moment at 56.1 degree to the direction of a 0.0791 -·T magnetic field, causing a torque of 0.00357 N m to act on it Find the magnitude of the magnet's magnetic dipole moment.
A neutron star is composed of neutrons and has a density that is about the equal as that of a nucleus. Determine the radius of a neutron star whose mass is one-fourth of the mass of the sun
Two point charges q = +10C are a distance 0:12 m apart. Calculate the electrostatic force on each charge
Three point charges, -6.2 x 10-9 C, -8.7 x10-9 C, and +7.9 x 10-9 C, are fixed atdifferent positions on a circle. The total electric potential atthe center of the circle is -1900 V. What is the radius of the circle?
In order to manufacture these coffee tables, the company would need to incur $525,000 in fixed costs for new equipment. Calculate the break-even point of the coffee tables in units sold.
A spherical balloon is partially blown up and its surface area is measured. More air is then added, increasing the volume of the balloon. If the surface area of the balloon expands by a factor of 6.7 during this procedure, by what factor does the ..
The vertical deflecting plates of a typical classroom oscilloscope are a pair of parallel square metal plates carrying equal but opposite charges. Typical dimensions are about 3.4cm on a side, with a separation of about 4.6cm . The plates are close e..
