10) An object is propelled upward at an angle e, 45° << 90°, to the horizontal with an initial velocity of vo feet per second from the base of a plane that makes an angle of 45° with the horizontal. If air resistance is ignored, th distance R that it travels up the inclined plane is given by the function vo22 R(O) = [sin(20) - COS(20) - 11. 32 Show that v02/2 R(O) = [sin (cos 0 + sin o)...

14. A wire holding a tower makes a 73° angle with level ground. At a point 30 feet farther from the tower than the base of wire (but on the same side as the base of the wire), the angle of elevation to the top of the tower is 35º, (see Figure (2) in the attachment Final Exam Figures.pdf).

HotWheels Launch Angle
HotWheels Launch Angle IntroductionIn this lab you are going to use the HotWheels Launcher and a ramp. The orange Hotwheels car launcher is a variable speed launch system with four settings. This makes it ideal for experiments to see the effects of velocity on projectile motion. You are going to launch a car with two different initial velocities at an angle and measure how far it lands. From the input data you can determine the initial velocity. Items needed: Measuring...

A crane is a type of machine mainly used to lift, lower, and horizontally move heavy objects. It is immensely useful in construction works. In this problem, we will be analyzing a type of crane called a luffing crane.

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

The Green Monster, as shown below, is a wall 37 feet high in left field at Fenway Park in Boston. The wall is 310 feet from home plate down the third base line. If the batter hits the ball 4 feet above the ground, neglecting air resistance, determine the minimum speed that the bat must impart to the ball that is hit over the Green Monster. COVIDIE CVS.
