A 21 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 2.3 kN/m. The block is pulled to the right so that the spring is stretched 9.4 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 46 N. \
(a) What is the kinetic energy of the block when it has moved 2.0 cm from its point of release?
The escape speed from a very small asteroid is only 26 m/s. If you throw a rock away from the asteroid at a speed of 39 m/s, what will be its final speed.
A 0.39 kg iron horseshoe that is initially at 745°C is dropped into a bucket containing 24 kg of water at 46°C. What is the final equilibrium temperature? Neglect any heat transfer to or from the surroundings.
Two bars of identical mass are at 32 °C. One is made from glass and the other from another substance. The specific heat capacity of glass is 840 J/(kg · C°).
Illustrate what gravitational force do the two protons in the helium nucleus exert on each other? Their separation is approximately 1.0 fm
A car of mass M = 800kg travelling at 50km/hour enters a banked turn covered with ice. The road is banked at an angle 20degrees, and there is no friction between the road and the car's tires.
Three equal point charges, each with charge 1.45?C, are placed at the vertices of an equilateral triangle whose sides are of length 0.650m
assume the roller coaster (h1 = 32 m, h2 = 11 m, h3 = 20) passes point A with a speed of 3.50 m/s. If the average force of friction is equal to one fifth of its weight, with what speed will it reach point B? The distance traveled is 30m.
If the piston has a cross sectional area of 0.0100 m^2 and negligible mass, how high would it rise when the temperature is raised to 250°C.
Three blocks, each of mass 12 kg are on the frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 1.1 m/s2. What is the net horizontal force on b..
determine the kinetic energy of the ball at its highest point. Illustrate what is its speed when it is 9.0 m below its highest point.
A ball m=1kg rolling without slipping on a flat surface with v=.1m/s strikes the wall after which v=.08m/s. What is the amount of heat generated due to impact?
Suppose the traffic light is hung so that the tensions T1 and T2 are both equal to 84.7 N. Find the new angles they make regarding the x axis. (By symmetry, these angles would be the same.)
