Atrunk of mass 16 kg is on the floor. the trunk has a very small initial speed. the acceleration of gravity is 9.8 m/s 2 . what constant horizontal force pushing thetrunk is required to give it a velocity of 10 m/s in 20 s if the coefficient of sliding friction between the trunk and the floor is 0.57? answer in units of n.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
