How would the angle between two vectors be found, if, for each vector, three components (i, j, k) were given?
Ex. Given that vector A = 2.0 i + 4.0 j - 7.0 k and vector B = 5.0 i - 3.0 j + 1.0 k, what is the angle between A and B?
I'm suppose to find the limit as x goes to infinity of [(9x + 1) ^ (1/2)] / [(x+1) ^ (1/2)].
L'Hopital's Rule does not work on here (it said so even in the directions) as the function keeps on cycling.
...they gave us the answer (3) but I need to find out how.
:S
A train slows down at a constant rate as it rounds a sharp circular horizontal turn. Its initial speed is not known. It takes 17.7 s to slow down from 68 km/h to 26 km/h. The radius of the curve is .184 km. As the train goes around the turn, (a) what is the magnitude to the tangential...
Well, to find the velocity, I'm using the distance after the string breaks as well as the time. How can I use those numbers when I'm trying to find the acceleration as the ball is still in the circular path. The situation is different once the string breaks. Wouldn't the velocity as ball is...
A ball on the end of a string is whirled around in a horizontal circle of radius .487 m. The plane of the circle is 1.06 m above the ground. The string breaks and the ball lands 2.26 m away from the point on the ground directly beneath the ball's location when the string breaks. The...
A ball is thrown from the top of a building upward at an angle of 66 degrees to the horizontal and with an initial speed of 8 m/s. The ball is thrown at a height of 34 m above the ground and hit s the ground 11.3347 m from the base of the building. The acceleration of gravity is 9.8 m/s^2...
The intensity L(x) of ligh X feet beneath the surface of the ocean satisfies the differential equation:
dL/dx = -kL
As a diver, you know from experience that diving to 18 ft in the Caribbean Sea cuts the intensity in half. You cannot work without artificial light when the intensity falls...
Particle 1 is moving on the x-axis with an acceleration of 5.45 m/s^2 in the positive x-direction. Particle 2 is moving on the y-axis with an acceleration of 7.56 m/s^2 in the negative y-direction. Both particles were at rest at the origin at t = 0 s. Find the speed of particle 1 with respect...
