The defender of a castle throws a rock off of the castle wall, releasing the rock at a point 10.4 m above the ground. The rock is thrown at 8.3 m/s at an angle of 27.5 ° below horizontal. What is the
It has a negligible thickness, located along the x-axis. Its ends have coordinates x= L and x=0. It also has a linear charge density λ= ax; a is just a constant. At an infinite distance, V =0. How do
Each intersection has a traffic signal, and the speed limit is 50km/hr . Suppose you are driving from the west at the speed limit. When you are 10.0m from the first intersection, all the lights turn g
Point charge 3.0microcoulombs is located at x = 0 m, y = 0.30 m, point charge -3.0 microcoulombs is located at x = 0 m, y = -0.30 m. What are the magnitude and direction of the total electric force th
Find a vector that points in the same direction as the vector (i + j) and whose magnitude is 1.
Through the power of repeatedly guessing I found the answer to be ( .707i + .707j ) but theres got to b
So there is a car being winched up onto a tow truck. It is on a ramp.
What are the main forces acting on the car?
On the vertical plane I know it is support and gravity.

A superhero flies 267 m from the top of a tall building at an angle of 21◦ below the horizontal. What is the horizontal component of the superhero’s displacement?What is the vertical component of the s
An electric vehicle starts from rest and accelerates at a rate of 2.3 m/s2 in a straight line until it reaches a speed of 15 m/s. The vehicle then slows at a constant rate of 1.1 m/s2 until it stops.
A rowboat crosses a river with a velocity of 3.58 mi/h at an angle 62.5° north of west relative to the water. The river is 0.870 mi wide and carries an eastward current of 1.25 mi/h. How far upstream
