While mountain biking you find you can accelerate from 0 m/s to 8 m/s in 3 seconds. What is your acceleration? Is this acceleration higher than that of the bear you are riding away from which accelerates from 0 to 30 m/s in 8 seconds?

What happens to the acceleration of and object if the net force that acts on it triples in magnitude?

According to the electromagnetic spectrum, a. long-wave radiation occupies a smaller percentage than short-wave radiation b. gamma rays and x-rays have long wavelengths. c. visible light waves have wavelengths of less than 1 micrometer. d.

A raindrop, mysteriously, falling on the Moon, hits thesurface at 57.4 m/s. The Moon's gravity is 1.6 m/s/s. Determine thetime that the drop is falling.

Suppose that you are visiting Champaign, IL and on July 10 you wake up early and note the rising azimuth of the Sun. How would the direction of the rising Sun change if you measured

A large electroscope is made with "leaves" that are 70 cm long wires with 19 g spheres at the ends. when charged, nearly all the charge resides on the spheres.

A boat with an anchor on board floats in a swimming pool that is somewhat wider than the boat. Does the pool water level move up, move down, or remain the same if the anchor is (a) dropped into the water or (b) thrown onto the surrounding ground

In July 2005, NASA's "Deep Impact" mission crashed a 372-kg probe directly onto the surface of the comet Tempel 1, hitting the surface at 37,000 km/h.

What conversion factor is needed to change from kilometres to meters

What does the law of universal gravitation state?

Estimate the smallest possible period of a satellite in a circular orbit around earth. (mass and radius of earth is 5.98 x 1024 kg and 6.37 x 106 m. the universal gravitational constant g = 6.67 x 10-11 n. m2/kg2.)
