1. An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per
second (ft./s). The height of the object off the ground is given by the formula
h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the
-16
object is propelled. The downward negative pull on the object is represented by
Solve for t.
A balloon, in the shape of a right circular cylinder, is being inflated in such a way that the radius and
height are both increasing at the rate of 3 cm/s and 8 cm/s, respectively. What is the rate of change
of its total surface area when its radius and height are 60 cm and 140 cm, respectively?

Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…arrow_forward
