Q$3/$ Given the circuit below with $3$ A of current running through the $4$ resistor as indicated in the diagram to the right. Determine the current through each of the other resistors.

Q$4/$ A ball thrown from the ground is given an initial velocity $30\frac{m}{sec}$ straight upward and after ball reach the maximum then down to the ground determine: $1-$time when the ball reaches maximum and the maximum height; $2-$ The velocity and the position of the ball at time $=4sec$;$3-$total time when the ball reach to the ground and velocity at this instant.

Q$5/$ A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launched at ground level with an initial velocity of $50ms-1$ at an angle of $45$ to the horizontal. Calculate: $1-$ The horizontal & vertical components of the velocity of the ball initially; $2-$ What is the maximum height that is achieved by the ball?;

$3-$How far from lunching point will the ball attain its original level and the total time when attain at original?
