Answer:
The initial speed of the ball is 23.3 m/s.
Explanation:
Given that,
Angle = 44°
Range = 55.7 m
We need to calculate the initial speed of the ball
Using formula of range

Where. u = initial velocity
r = range
g = acceleration due to gravity
Put the value into the formula




Hence, The initial speed of the ball is 23.3 m/s.
In a parallel circuit, the total power supply current is the sum of the
currents through all of the individual branches.
The output current (not the voltage) of the power supply is 5 A.
So the individual currents in the circuit branches is 5 A.
The current through the first 2 resistors is (1 + 0.5) = 1.5 A.
So the current through the 3rd resistor is (5 - 1.5) = <u>3.5 A</u>.
