A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. There is friction between the ramp and the block as it slides a distance x up the ramp and then slides back down. On the dots below, which represent the block as it is sliding up the ramp and down the ramp, draw and label
the forces (not components) exerted on the block. Represent each force by a distinct arrow starting on, and
pointing away from, the dot. The dashed lines are drawn at the same angle as the surface of the ramp.
Up the Ramp
Down the Ramp

1. how much energy is needed to raise the temperature of 40.0 g of argon from 25c to 40c? the specific heat capacity of argon is 0.520 j/(g·k) 2a. 23.0 ml of 0.100 m hcl (standard) are added from a buret to neutralize 50.0 ml of an unknown basic solution. 2b. if the oh- produced in the previous reaction came from ca(oh)2, then what is the molarity of the ca(oh)2? 3.calculate the new freezing-point of a solution when 60.5 grams of cacl2 solute is dissolved in 0.612 kg of water. 4. what is the maximum number of moles of alcl3 that can be produced from 5.0 mol al and 6.0 mol cl2? 5. a sample of oxygen gas has a volume of 150 ml when its pressure is 0.923 atm. if the pressure is increased to 0.987 atm and the temperature remains constant, what will the new volume be? 6. nitrogen gas in a closed container at a temperature of 100.0 oc and 3.0 atm is heated to 300 oc. what is the pressure of the gas at the higher temperature?
