    Calculate the amount of work required to assemble a system of charges.

    Homework Statement The three charges shown below (Q1=22.6*10^-6C, Q2=22.6*10^-6C, Q3=61.0*10^-6C) are at the corners of an iscoceles triangle with sides a=4 m and b=2 m. Q3 is 2m from Q1 and Q2, Q1 is 4m from Q2. In other words, Q3 is the point charge at the "tip" of the isosceles...

    Basketball Vector/Kinematics Question

    I know that it is 2.1 metres from the ground when it starts and the end-point is 2.6 metres from the ground and 11 metres away from the start. Therefore: X0 = 0m, X1 = 11m, Y0 = 2.1m, Y = 2.6m The ball is being released at a 38 degree angle, my thought process was to get either one of the...

    Basketball Vector/Kinematics Question

    Parabolic? I tried to separate it into two (horizontal and vertical) components so that I could then work out the actual velocity. And then tried to work each of them out individually. I don't even know if that's the right way to go about doing it because it feels like I am missing one of the...

    Basketball Vector/Kinematics Question

    Homework Statement A basketball leaves a player's hands at a height of 2.10metres above the floor. The basket is 2.60metres above the floor. The player likes to shoot the ball at a 38 degree angle. If the shot is made from a horizontal distance of 11.00metres and must be accurate to...
