For the three vectors A+B+C= -1.4i. Vector A is 4i and vector C is -2j. Write vector B as components separated by a comma. What is the magnitude of vector B? How many degrees above the negative x-axis does vector B point? Measure the angle clockwise from the negative x-axis.
Let s(t) represent the position of a particle at time t, v(t) is the velocity and a(t) is the acceleration. What is the value of v(9) for the following: Given that the acceleration of the particle at time t is a(t) = -3t^2+ 3t + 10 and that its position when t = 1 is s(1) = 1 ...

Consider the function f(x)=-((x^2)/2)-9. In this problem you will calculate integrate from 0 to 3 of ((-x^2)/2)-9)dx by using the definition integrate from a to b of (f(x))dx= lim as n approaches infinity of sum_(i=1)^n of (f(x_i))(delta x) The summation inside the brackets is...

Is this true or false? All objects moving in a circle are accelerated. I really dont uderstand this question.

Anne throws a ball straight up releasing it from her hand with an initial speed of 20 m/s. The ball is at a height of 1.5 m above the ground when it is released. Determine the maximum height of the ball? Calculate the balls speed just before it hits the ground?
Hi, ive been trying to get this problem for a couple of days now but i have no idea of what to do. A very slippery block of ice slides down a smooth ramp tilted at angle pheta. a)The ice is released from rest at vertical height h above the bottom of the ramp. Find an expressio...
You have two balloons, one large (30 cm in diameter) and one small (15 cm in diameter) filled with helium. Both balloons are made of the same material (latex) and have the same unfilled material thickness (2 mm) and have a 3 cm diameter. You release both balloons at sea level ...
