Answer:

θ = 56.09°

Explanation:

Given that

h = 8.5 ft

speed ,u= 28 ft/s

We know that acceleration due to gravity g

g= 32.2 ft/s²

The maximum height h is given as

h=\dfrac{u^2sin^2\theta}{2g}

Now by putting the values

8.5=\dfrac{28^2sin^2\theta}{2\times 32.2}

sin^2\theta=0.69

sin\theta=0.83

θ = 56.09°

Therefore the angle will be θ = 56.09°

With the switch open, roughly what must be the resistance of the resistor on the right for the current out of the battery to be
Delvig [45]

Answer:

The resistance must be 6.67\Omega

Solution:

Resistance, R_{1} = 20\Omega

Resistance, R_{2} = 10\Omega

For the current to be the same when the switch is open or closed, the resistances must be connected in parallel as current is distributed in parallel with the same voltage across the circuit:

Thus in parallel:

\frac{1}{R_{eq}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}

\frac{1}{R_{eq}} = \frac{1}{20} + \frac{1}{10}

R_{eq} = 6.67\ \Omega
