Temperature An object at a temperature of 80C is placed in a room at 20C . The temperature of the object is given by T=20+60e0.06m where m represents the number of minutes after the object is placed in the room. How long does it take the object to reach a temperature of 70C ?
The Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?
New Equation of Change? The tax liability T in dollars, for a company that has an initial tax liability of 6200 is dTdt=0.02T. Here, t is time in years. What would be the equation of change for the tax liability if the initial tax liability were 7000?
Kinetic Energy The kinetic energy E of an object can be calculated by the formula E=12mv2, where m is the mass and v is the velocity. Solve for m.
Speed of a Skidding Car Police use the formula s=30fd To estimate the speed s (in mi/h) at which a car is traveling if it skids d feet after the brakes are applied suddenly. The number f is the coefficient of friction of the road, which is a measured of the “slipperiness” of the road. The table gives some typical estimates for f . If a car skids 65 ft. on wet concrete, how fast was is moving when the brakes were applied? If a car is traveling at 50 mi/h, how far will it skid on wet tar?
