he 5.0- block is pulled to the right with a force as shown in the figure . The coefficient of static friction between all surfaces is 0.55 and the kinetic coefficient is 0.3, illustrate what is the minimum value of needed to move the two blocks?
The moon in its orbital about the earth has a centripetal acceleration about 1/4200 of that an object dropped on Earth's surface. If the moon were twice as far away what would its centripetal acceleration be?
A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is ..
Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you find in part (a). Illustrate what should be the maximum speed of the car so it can round the curve safely?
find the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
At what coordinate on the axis is the net electric field produced by particles equal to zero.
An oscillator with a mass of 420 g and a period of 0.900 s has an amplitude that decreases by 1.90 percent during each complete oscillation.
Walk 10 miles in the direction 54 degrees east of due north. Then walk 4 miles in the direction 23 degrees south of due east. How far will you be from your starting point?
ball rolls horizontally off the edge of a tabletop that is 1.80 m high. It strikes the floor at a point 1.32 m horizontally away from the table edge. (Neglect air resistance.) (a) How long was the ball in the air? s (b) What was its speed at the i..
