A block of mass m = 331 g is dragged with a string across a ro9h horizontal table. The string tension is T= 3.43 N, and it pulls upward at an angle of phi = 48.0 degree with the horizontal. At one particular instant the block is moving at a speed of y = 5.1 m/s. The coefficient of kinetic friction between the block and the table is mu kj = 0.699. What is the power supplied to the block...

1- A 300 ? mass is attached to
a solid 40 ?? long string the other end of which is secured to the
ceiling. The mass is given an initial speed which makes it swing
around a circular path in the horizontal plane without changing its
speed and without changing its height. The object completes 2
revolutions in 2 seconds.

You plan to fly a model airplane of mass 0.550 kg that is attached to a horizontal string. The plane will travel in a horizontal circle of radius 5.10 m. (Assume the weight of the plane is balanced by the upward "lift" force of the air on the wings of the plane.) The plane will make 1.10 revolutions every 3.50 s. (a) Find the speed at which you must fly the plane. (b) Find the force exerted on your hand...

A small plasticl ball is tied to a very light 26.0 cm string that is attached to the vertical wall of a room. A uniform horizontal electric field of magnitude 36,000 N/C exists in this room. When the ball has been given an excess charge Q = -1.10 uC, you observe that the ball remains suspended, with the string making an angle of 17.4 degrees with the wall. A) What is the direction the electic field E in the room?...

A uniform meter stick of mass 1.5kg is attached to the wall by a frictionless hinge at one end. On the opposite end it is supported by a vertical massless string such that the stick makes an angle of 40 degrees with the horizontal. Find the tension in the string and the magnitude and direction of the force exerted on the stick by the hinge.

co200.000 10.5 A block of mass 0.5 kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50 N/m. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the spring is unstretched, the block is located at x = Om. The block is then pulled to x = 0.3m and released from rest so that the block-spring system...
