11. Using propagation of error method, derive an expression for uncertainty in acceleration, oa. Hint: a = a(dt).

Using the definition of the scalar product, find the angle between the following two vectors: A = -2î + 4ĵ , B = 3î – 4ĵ + 2k.

This is on other question I cannot figure out on the quizlet. Thanks for your help

If Force = (- 7, 9) and displacement = (-2,-2 ), find the work done from the two vector measurements .

Given: The energy equivalent of one gallo of gasoline is 1.3 x 10 J. A compact car has a mass of 907 kg, and its efficiency is rated at 16.7%. (That is, 16.7% of the input energy available is delivered to the wheels.) Find the amount of gasoline used to accel- erate the car from rest to 25.1 Answer in units of gal. m/s.

Let a bag of mass 'm' is being raised to a height 'h' from the floor of your classroom. Whatwill be the work done by the applied force (Fa) and gravitational force (Fg)?

The dot product (3i - j)•B is?

. Use the definition of scalar product, a two vectors given by a = 5.0 + 5.0 b = ab cos 0, and the fact that a b = axbx + aby + a2b₂ to calculate the angle between the + 5.0k and b = 7.01 +3.0 + 3.0k.

This is a multiple choice with 3 parts so all parts need to be answered. They are not separate questions so this is not against guidelines. Please just give me the number of the questions and the letter of the answer, no need to do too much work. Thank you!!!

Find the displacement Work done=0.08 J Force=3.221 N
