A ship carrying freshwater to a desert island in the Caribbean, hasa horizontal cross-sectional area of 2600m^2 at thewaterline. When unloaded, the ship rises 8.50m higher in tehsea. How much water was delivered?
Illustrate what is the speed of the three coupled cars after the collision? How much kinetic energy is lost in the collision?
A massless spring of constant k = 1000 N/m is fixed on the right side of a level track. A block of mass m = 1.50 kg is pressed against the spring, compressing it a distance d =20.0 cm. The block (initially at rest) is then released and travels tow..
Determine the maximum energy lost in the collision.
A transverse wave on a string is described by the following equation, where x is in meters and t is in seconds. y = (0.130 m) sin ?(x/8 + 5t), What is its speed of propagation
A 45 kg trunk is pushed 7.8 m at constant speed up a 30° incline by a constant horizontal force. calculate the work done by the applied horizontal force
The sound level in decibels is typically expressed as ? = 10 log (I/I0), but since sound is a pressure wave, the sound level can be expressed in terms of a pressure difference. Intensity depends on the amplitude squared, so the expression is ? = 2..
A car initially traveling at 23.2 m/s undergoes a constant negative acceleration of magnitude 2.10 m/s2 after its brakes are applied. (a) How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the ..
Waly Whacko claims to have invented a heat engine that will revolutionize industry. What error did he made in his choice of temperature scale
At NASA's Zero Gravity Research Facility in Cleveland, Ohio, experimental payloads fall freely from rest in an evacuated vertical shaft through a distance of 132 m. How fast will the payload be traveling when it reaches the bottom of the shaft
The company adheres to a 60% dividend payout ratio and has a P/E ratio of 19. There are 21,000 shares of stock outstanding. Illustrate what is the amount of the annual net income for the firm?
An automobile engine with an efficiency 0.21 dumps heat to the environment at the rate of 460 kW. What's its mechanical power output in W? What's its mechanical power output
A spring is resting vertically on a table. A small box is dropped onto the top of the spring and compresses it. Determine the magnitude of the spring's displacement at an instant when the acceleration of the box is zero
