Starting from rest, a boulder rolls down a hill with constant acceleration and travels 4.00m during the first second.
A) How far does it travel during the second second?B) How fast is it moving at the end of the first second?C) How fast is it moving at the end of the second second?
Compared to an object that does not roll, other than instead slides without friction, should a rolling object be released from same, a greater, or a lesser height in order just barely to complete the loop the loop.
The racket is a potential-energy barrier whose height is the energy of the slowest string-breaking ball. Suppose that a 100 g tennis ball traveling at 220mph is just sufficient to break the 2.0-mm-thick strings.
A 16.0 microF capacitor and a 5.20mH inductor are connected in series with an open switch. What is the angular frequency of the charge oscillations in the capacitor after the switch is closed
The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end, What is the skier's launch speed
A hard steel ball is dropped from rest at postion y = 2h and bounces from a hard surface tilted at an angle phi from horizontal. On impact, Find the horizontal displacment of the ball
Two long parallel wires each with a mass per unit length of 25.10 g/m are supported in a horizontal plane by 2.5 cm long strings. Each wire carries the same current, I, causing the wires to repel each other so that the angle between supporting string..
A 30.0 capacitor initially charged to 30 is discharged by a 1.40 resistor. How long does it take to reduce the capacitor's charge to 2.00.
A hollow sphere of radius 0.35 m, with rotational inertia I = 0.032 kg m2 about a line through its center of mass, How much of this initial kinetic energy is rotational
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
A new electric power plant has an efficiency of 42%. how many are essentially lost as waste heat (in barrels of oil) to the environment
A cart with mass 200gmoving on a frictionless linear air track at an initial speed of 1.1m/sundergoes an elastic collision with an initially stationary cart of unknown mass. What is the speed of the two-cart center of mass
Compare the speed of sound following from that slope to the calculated speed of sound from the gas properties
