1.A roofer is dreagging a 15.0kg bundle of shingles up a roof at a constant speed.The roof is sloped at an angle of 30o with respect to the horizontal. d)Calculate the force parallel to the roof with which the roofers must pull on the rope to move the shringles at a constant speed up the roof.Answer to 3 significant digits. e) Suppose an astronaut was building a similar structure on Mars.What would be the force component perpindicular to the roof of the weight of a 15.0 kg bundle of materials on the surface of Mars? The mass of Mars is 6.42x1023kg and the radius of mars is 3.30x106 m. Answer to 3 significant digits
