Q. An airplane has a speed 530. If wind begins blowing from the southwest at the speed of 94. In what direction should the pilot aim the plane so that it will fly due south?
Q. WebAssign will do simple calculations for you, using +, -, *, /, parentheses, and E-notation. For instance, if a question asks for half the sum of 246 and 388, you can enter "(246+388)/2". For more complicated calculations you will need to make use of a calculator and then enter your result. What is the product of 110 and 120?
Carry out the following arithmetic operations: (a) sum of the measured values 756, 37.2, 0.83 and 2.5. The answer must be in significant digits. Since 2.5 and 0.83 have two significant digits, shouldn't the answer be 800 instead of 797.
What is the coefficient of kinetic friction between the crate and the floor. what height will the stream of water strike.
How far from a point on the floor directly below the edge. Why is it a good idea to have your hand extended forward when you are getting ready to catch the fast moving baseball with your bare hand.
A uniform plank of length 4.3 m and weight 201 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x could a person who weighs 449 N walk on the overhanging part of the p..
