1. A box rests on a 30 degree incline at a height of 3 meters. Determine the work done by friction as the object slides down the incline, given that the coefficient of friction between the box on the incline is 0.45. For the box in the previous problem, what will the speed of the box be at the bottom?A roller coaster has an initial hill of height "h". If the coaster slides down and then rolls through a loop of radius "r" at the bottom of the hill, how much larger must "h" be than "r" in order for the roller coaster to not lose contact with the track at the top of the loop?

A box is sliding up a 40 degree incline. At a point 55cm from the bottom of the incline (measured along the incline) the phone has a speed of 1.4ms^-1. The coefficient of kinetic friction between the box and incline is 0.15. a) Write expressions for Newton's second law in directions parallel and perpendicular to the surface of the incline. Thus show that the box will move a further 13cm up the incline. b) After having stopped, the phone slides...

1. Assume alleles of the height gene of corn plants determine the height of the plant's stalks, and that there are two alleles of the gene: "H1" and "H2." Individuals that are homozygous for the "H1" allele are 10 feet in height, individuals that are homozygous for the "H2" allele are 6 feet in height, and heterozygotes for these two alleles are 6 feet in height. From this data, it can be concluded that, with respect to the "H1" allele,...
