### If a footballer kicks a ball straight down the pitch at 6 ms-1 at an angle θ of 30° above the horizontal, what is the maximum height reached by the ball?

First we must remember our equations of motion, (SUVAT equations).S = Displacement U = Initial velocity V = Final velocity A = Acceleration T = TimeV = U + ATS = UT + (1/2)AT2

### A circuit with a cell of voltage 6V and two resistors of resistance 6 Ohms each connected in parallel. What is the current through the Cell?

Step 1 - draw the circuit.
Step 2- Finding total resistance of resistors in parallel, 1/Rt = 1/R1 + 1/R2 where Rt is the total resistance of the circuit.
Step 3- Use Ohms laws...

### A tall 2 meter tall basketball player shoots for the net that stands 3 meters from the ground. If he throws he ball from head height at an angle of 60 degrees and the ball travels at 10 meters per second, how far away is the hoop?

By taking the initial vertical speed as vv = 6 sin(60) = 5.2 ms-1.The max height of the ball is given by vv2 = uv2 + 2as. From this, s = 1...
