An airplane must reach a speed of 197 mi/h to take off. If the runway is 462 m long, what is the minimum value of the acceleration that will allow the airplane to take off successfully?

Use the sine function to determine how long of a board you need to use to make a ramp that just reaches the 1.00- high truck bed at a 40 angle to the ground.

A slide projector needs to create a 80 cm high image of a 2.0 cm tall slide. The screen is 240 cm from the slide. Assume that it is a thin lens.

A hotel elevator ascends 110 {\rm m} with a maximum speed of 4.0 {\rm m/s}. Its acceleration and deceleration both have a magnitude of 1.2 {\rm m/s^2}.

Calculate the magnitude of the gravitational force exerted by Mercury on a 65 kg human standing on the surface of Mercury. (The mass of Mercury is 3.31023 kg and its radius is 2.4106 m.)

A solid cube with the length of each side equal to 2.19 cm has a mass of 7.6 g. What is the density of the cube in kg/m3?

at rest, a light source emits 532 nm light. as it moves along a line connecting it and Earth, observers on Earth measure the wavelength to be 412 nm. What is the sources velocity and direction?

A 150 g copper bowl contains 130 g of water, both at 20.0 C. A very hot 380 g copper cylinder is dropped into the water, causing the water to boil, with 13.0 g being converted to steam. The final temperature of the system is 100 C. Neglect energy transfers with the environment. (a) How much...

Two crates, of mass 65 kg and 125 kg, are in contact and at rest on a horizontal surface (see figure). A 650 N force is exerted on the 65 kg crate. The coefficient of kinetic friction is 0.12. (a) Calculate the acceleration of the system. m/s2 (to the right) (b) Calculate the force...
