Three resistors with values of 60.0Ω, 30.0Ω, 20.0Ω, respectively, are connected in series to a 110.0 V battery of negligible internal resistance. Draw a circuit diagram and find the (a) equivalent resistance of the combined resistors, (b) current flowing through each resistor,
(c) voltage drop across each resistor, and (d) the power dissipated by each resistor.
a projectile is fired from a point at125m/s so as to strike a point a horizontal distance of 100m and 200m higher than the point of firing neglecting air resistance, calculate (a) the angle with the horizontal, at which the projectile should be fired in order to strike the point in minimum time (b) the time taken by the projectile to strike the point
an arrow leaves a bow at 25m/s (a) what is the maximum range? (b) at what two angles above the the horizontal can it be sent to reach target 50m away?
