A basketball rolls off of the roof of a house with a velocity of15 m/s. The roof makes an angle of 23 degrees with the horizontal. If the edge of the roof is 10 meters high, clarify how far from the base of the house the basketball hits.
In a parallel plate capacitor, two plates are being discharged by a constant current. Each plate has a radius of 4.0 cm. During the discharging, at a point between the plates at radial distance 2.0 cm from the central axis, the magnetic field has ..
A shop sign weighing 245-N is supported by a uniform 155-N bean. Find out the tension in the guy wire, and the horizontal and vertical forces exerted by the hinge on the bean.
Determine the vertical component. when would a microphone at the other end first detect a disturbance.
A bag of cement of weight 375 N hangs from three wires as suggested in Figure P5.18. Two of the wires make angles θ1 = 55.0° and θ2 = 25.0° with the horizontal. If the system is in equilibrium, find out the tensions in the wires.
A tennis ball is thrown toward a vertical wall with a speed of 22.0 m/s at the angle of 40.0° above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 28.0 m.
You drop a stone into a deep well and hear it hit the bottom 2.40 s later. This is the time it takes for the stone to fall to the bottom of the well, plus the time it takes for the sound of the stone hitting the bottom to reach you. Sound travels ..
Suppose a hanging 1 kg lab mass is attached to a 4.0 kg block on the table. If the coefficient of kinectic friction, mu is 0.20, what is the acceleration of the block.
The bullet becomes embedded in the block. if the coefficient of kinetic friction between the block and surface is .65 what was the speed of the bullet at once before impact.
A 1.20 brick is sliding next to on a rough horizontal surface at 15.0 .If the brick stops in 4.30, how much mechanical energy is lost?
From another measurement, you have found that velocity of the jumper's center of mass has only a y component of v2=2.5 m/s as the jumper's feet leave the floor.
A uniform magnetic field of magnitude B= 1.2 teslas is directed toward the bottom of the page in the -y direction as shown above. At time t=0, a proton p in field is moving in the plane of the page with a speed v0= 4 x 10^7 meters per second in a ..
An airplane is flying with a velocity of 91at an angle of 26 above the horizontal. When the plane is a distance 107 directly above a dog that is standing on level ground, a suitcase drops out of luggage compartment.
