I'm not sure if there is a rest of the question. We were just assigned to perform an experiment. We decided on seeing how little a mass we need to move a person who is 63.5 kg and I've been trying to use physics to develop a supported hypothesis before we started. That is all the information I...

To find the height, use the triangle created when it is pulled back 60 degree. Measure the vertical height from the object to ceiling(or whatever the top is) and then just use some basic trig or the Pythagorean theorem.

B = \muoI/2\pir B is magnetic field, I is current, r is radius of the magnetic field(i think), and \mu0 is equal to 4\pi x 10-7 Those pi's aren't superscripted, it is just being difficult.

Homework Statement What is the smallest possible mass needed to move a 63.5 kg mass? To find this, I need to know the force need to move the known mass, time the unknown mass stays in contact with the known mass, and velocity at which the unknown mass is traveling. I believe I can find out the...

I am given the information that a nerf dart is launched upwards at a 90 degrees with the top of the launcher at 1.953ft and that it hits the ground .43 seconds later. I am then tasked with finding the initial velocity of the launcher and I have no idea where to start.
