Homework Statement The goal of my lab was to measure the ratio of charge to mass for electrons (e/m) and the approximate ambient magnetic field of the Earth (BE). I have come up with what is the required equation (my TA confirmed this) but I am having trouble linearizing it. y=mx+b...

Thank you for your help! I understand what to do now.

Thanks for the quick reply! I substituted all my v0=100 and simplified to get this: -0.5*-9.81(16/1+(tan(theta))^2) + 400*tan(theta) -150=0 Edit: I'm not sure entirely how I would simplify further.

Homework Statement A cannon is fired at a target on a cliff that is 400 meters away. The cliff has an elevation of 150 meters relative to the cannon. The initial velocity of the cannonball is 100 m/s. Ignoring wind resistance calculate the two possible angles and their respective times. X=...
