A ball is thrown upward with a velocity of 160 feet per second. The position at any time t (seconds), after the throw, can be computed using the formula y(t) = 160t-16t^2 feet When does the ball reach maximum height? Hint: The ball reached maximum height when the velocity is zero
A ball on a spring is pulled 4 inches below its rest position and then released. After t seconds, the ball’s distance, d, in inches from its rest position is given by d = -4cos π/3t. Solve, Find all values of t for which the ball is 2 inches below its rest position.
A group of athletes were tested for isometric endurance by measuring the length of time they could resist a load pulling on their legs while seated. The approximate amount of time (called the holding time) that they could resist the load was given by the formula t=31,293w^-2.5,where w is the weight of the load in pounds and the holding time t is measured in seconds. a. Determine the holding time for a load of 32lb. b.When the weight of the load doubled, by what factor is the holding time changed?
