A cylindrical container of inside diameter 0.6 m is filled with gasoline to a depth of 2 m. What is the mass of the gasoline?
You and a friend each drive 67 km. You travel at 88.1 km/h, your friend at 952.6 km/h. How long would your friend wait for you at the end of the trip.
A bullet of mass 0.0025 kg moving at 581 m/s impacts a large fixed block of wood and travels 5.40 cm before coming to rest.
A 4.25 bullet traveling horizontally with a velocity of magnitude 375 is fired into a wooden block with mass 1.10 , initially at rest on a level frictionless surface. The bullet passes by the block and emerges with its speed reduced to 110 .
An aquarium contains a 5-cm layer of water (n = 1.333) floating on top of carbon tetrachloride (n = 1.461). If an angle of incidence into water from the carbon tetrachloride is 20, what is the angle of refraction into the air.
Chromium is produced by reacting its oxide with aluminium. If 354 g of Cr2O3 and 158 g of Al react to form 204 g of Al2O3, how many grams of Cr are formed.
A chocolate bar (40grams) has 210 Calories. Approximately how long would the 100 watt light bulb shine if we convert all the chocolate's energy into electricity (100% efficiently)? (Remember 1Cal = 1000 cal = 4200 joules)
The force of the wind on the sails of a sailboat is 300 N north. The water exerts a force of 210 N east. If the boat (including crew) has a mass of 310 kg, illustrate what are the magnitude and direction of its acceleration?
The altitude of a hang glider is increasing at a rate of 6.80 m/s. At the same time, the shadow of the glider moves along the ground at a speed of 15.5 m/s when the sun is directly overhead. Calculate the magnitude of the glider’s velocity.
Calculate the electrostatic force exerted on the point charge by the cylinder and what level of uncertainty would be acceptable in the initial position? You may assume that the uncertainty in all other parameters is negligible
The car that hits a concrete barrier and takes 0.3 seconds to stop.
An air puck of mass m1 = 0.30 kg is tied to a string and allowed to revolve in a circle of radius R = 1.0 m on a frictionless horizontal table. The other end of the string passes by a hole in the center of the table, and a mass m2 = 1.20 kg is att..
An 8-g bullet is fired into a 170 g block that is initially at rest at the edge of a table of 1m height. The bullet remains in the block, and after the impact the block lands d = 2.10 m from the bottom of the table. Determine out the initial speed..
