! 1 Question 10 of 14 View Policies Current Attempt in Progress Q A 1 option A jogger travels a route that has two parts. The first is a displacement A of 2.30 km due south, and the second involves a displacement B that points due east. The resultant displacement A + B has a magnitude of 3.95 km. (a) What is the magnitude of B, and (b) what is the direction of A + B as a positive angle relative to due south? Suppose that A - B had a magnitude of 3.95 km. (c) What then would be the magnitude of B, and (d) what is the direction of A - B relative to due south?

The laboratory balances have a precision of 0.01g. If you are obtaining the mass of an approximately 5 gram sample, which of the following is a proper way to record this measurement in your laboratory notebook and on your report sheets.     4.92 g     4.92     4.925 g     5.00 g

Suppose a projectile is fired with initial speed v, and angle e above the horizontal. a) Understand and plan. Draw a picture, establish a coordinate system for this problem and label your diagram. Make a table of known/given information and unknown/wanted information (this may involve reading the rest of the problem before starting). b) Using Kinematics, derive a symbolic expression for the maximum height reached by the projectile. Check the physical units of your expression. c) Using Kinematics, derive a symbolic expression for the total time the projectile is in the air. Check the physical units of your expression. d) Using Kinematics, derive an expression for the magnitude and direction angle of the projectiles velocity a time t after the object is fired. Check the physical units of your expression. e) Suppose that the projectile is fired with an initial speed of v, = 46.6 m/s and 0 = 42.2°, what is the magnitude and direction angle of the projectile's velocity t = 1.50 s after…

The figure shows two dots of a motion diagram and vector 7₁. Draw the next velocity vector 2 if the acceleration vector a at dot 2 points up. Draw the vector starting at the black dot 2. The location and orientation of the vector will be graded. The exact length of your vector will not be graded but the length relative to vector v₁ will be graded. + Σ B No elements selected I Select the elements from the list and add them to the canvas setting the appropriate attributes. i ?
