A 5.5 kg bowling ball initially at rest is dropped from the top of a 12 m building. It hits the ground 1.75 s later. Find the ne
Thepotemich [5.8K]

We are given that:

m = 5.5 kg

d = 12 m

t = 1.75 s

Using the distance formula, we can get the acceleration of the ball:

d = (1/2) a*t^2

Rearranging:

a = 2d/t^2 = 2*(12 m)/(1.75 s)^2

a = 7.837 m/s^2

 

<span>Using Newton’s 2nd law, force is defines as:</span>

F = ma

F = 5.5 kg (7.837 m/s^2)

<span>F = 43.10 N</span>

aleksandr82 [10.1K]

Answer:

EMF of the power source, E = 19.34 volts

Explanation:

It is given that,

Voltage at which computer sensor is operated, V = 11.7 V

Power, P = 26.37 W

Total resistance of the power source, R = 2.23 Ohms

Firstly, calculating the current in the circuit. It is calculated as :

P=I^2R

I=\sqrt{\dfrac{P}{R}}

I=\sqrt{\dfrac{26.37}{2.23}}

I = 3.43 A

Let E is the emf of the power source. It is given by,

E=V+IR

E=11.7+3.43\times 2.23

E = 19.34 volts

Hence, the EMF of the power source is 19.34 volts. Hence, this is the required solution.
