Question 3 A spherical balloon with radius r inches has a volume V(r) = 4 3 πr3. (a) Find an expression for the amount of air required to inflate the balloon so that the radius increases from r to r+3. (b) Find an expression for the amount of air required to double the radius of the balloon from a radius of r to a radius of 2r. (c) If the balloon starts with a volume of 36π cubic inches and the radius is increasing at 1 inch per minute, then how long will it take for the balloon to inflate to a volume of 200 cubic inches?

Given: A homogeneous quarter-circle block (with a radius of R and a weight of W ) is supported by a rough, horizontal floor, as shown.. A force P is applied to the block at corner B. Find: For this problem: a) Determine the x-location of the normal force acting on the block by the floor. Express your answer in terms of R. b) What is the minimum coefficient of static friction between the block and ground, μs, that is required to prevent motion of the block? c) Is the block in a state of impending slipping or tipping for the value of μs found in b) above? Explain. For this problem, use: P = W.
