a) Calculate the angular momentum of a solid uniform sphere with a radius of 0.145m and a mass of 14.0kg if it is rotating at 6.35rad/s about an axis through its center.
b) Calculate kinetic energy of a solid uniform sphere with a radius of 0.145m and a mass of 14.0kg if it is rotating at 6.35rad/s about an axis through its center.
A 650 kg weather balloon is designed to lift a 4600 kg package. What volume should the balloon have after being inflated with helium 0 degrees Celsius and 1 atm pressure to lift the total load.
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
A 0.280 kg ball is dropped from rest at a point 1.35m above the floor. The ball rebounds straight upward to a height of 0.780 m. What are the magnitude and direction of impulse of the net force applied to the ball during the collision with the flo..
A spring of k=12.00 N/m has a block of mass 11- kg attached to it on a frictionless table. If the block is pulled a distance 0.17m to the right and released from rest, how long would it take the block to return to its equilibrium position? Give yo..
Two charged dust particles exert a force of 8.5 x10-2 N on each other. What will be the force if they are moved so they are only one-seventh as far apart.
Two sound sources driven in phase by the equal amplifier are d = 4 m apart on the y axis. At a point a very large distance from the y axis, constructive interference is first heard at an angle θ1 = 0.140 rad with the x axis.
What are the velocities of the two people after the snowball is exchanged. What is the greatest kinetic energy of the electrons removed from the cathode by this light.
Two 24 cm focal-length converging lenses are placed 16.50 cm apart. An object is placed 39.0 cm in front of one. Where would the final image formed by the second lens be located.
An airplane whose air speed is 608 is supposed to fly in a straight path 38 north of east. But a steady 86 wind is blowing from the north. In what direction must the plane head.
