Atruck traveling down the mountain loses its brakes. fortunately, just ahead is a runaway truck ramp, which slopes uphill at an angle of 35 degrees from horizontal. the truck has a mass of 9000 kg and is moving at a speed of 110 km/hr just before starting up the ramp. the ramp is covered with gravel to provide a lot of friction, giving an effective coefficient of kinetic friction ௞ ൌ 0.60. using the work‐energy theorem, calculate how far up the ramp the truck goes before stopping. give the distance along the ramp, not the vertical rise.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

True or false graphs must include scales that increase by the same amount
