A delivery truck travels 29 blocks north, 18 blocks east, and 26 blocks south. Assume the blocks are equal length.
a) What is the magnitude of its final displacement from the origin?
b) What is the direction of its final displacement from the origin?
A 3 kg block is observed to accelerate at a rate twice that of the 6 kg block. Is the net force acting on the 3 kg block therefore twice as large as that performing on the 6 kg block? Explain.
Soccer ball is kicked with a speed of 11.50 m/s at an angle of 30.0° above the horizontal. If the ball lands at the same level from which it was kicked, how long was it in the air.
In a non-uniform gas, the equation of state is valid locally, as long as the density does not change too rapidly with position. Consider a column of ideal gas under gravity at constant temperature. Find the density as a function of height, by bala..
