Assuming origin to be at the point of projection and downwards being the direction of #-hatj#. For ball # (b)# ignoring air friction kinematic expression is #v^2-u^2=2gh#

Dec 22, 2015 · For u and v to be orthogonal, their inner product must be 0. The dot product of <3, -2> and <4, b> is (3*4)+ (-2*b) Set this equal to 0 and solve to get 12-2b=0rArrb=6.

1.80 * 10^(22) "atoms" You should know that in order to get from grams to atoms, you need to go through moles first. So you will need to use the molar mass of barium chloride to convert the …

Density is the mass per unit of volume of a substance. Density is measured in mass units over volume units. In this problem, the mass unit is grams, and the volume unit is "cm"^3. The …

How do you use Heron's formula to find the area of a triangle with sides of lengths #15 #, #16 #, and #12 #? How do you use Heron's formula to find the area of a triangle with sides of lengths …

Both the components are orthogonal to each other and therefore independent. It is clear that initially he will rise up and then start falling down due to action of gravity. The acceleration due …

And thus a formula of C_6H_12 corresponds to a ring OR an olefin bond, i.e. 1^@ of unsaturation. If we put oxygen in the formula, C_6H_12O, we could have a carbonyl or formyl functionality, …

Take the cross product of the two vectors. Normalise that resultant vector to make it a unit vector (length of 1). The unit vector, then, is given by:

Projection of a given vector u on another vector v is the scalar multiple of vector v, given by the formula projvu = → u.→ v ∣∣→ v ∣∣2 → v The required projection would thus be 0.3 − 2.7 − 2.4 …

Questions and Videos on 2-D Vectors, within PrecalculusLet #veca=<−2,3># and #vecb =<−5,k>#. Find #k# so that #veca# and #vecb# will be orthogonal. Find k so that →a and →b …
