Answer:

t = 2.44 s

Explanation:

Given that,

A stunt man climb up 29.4 meters into a cannon. He gets fired horizontally out of the cannon with a speed of 57.1 m/s.

We need to find the time for which was the stunt man in the air. Let it is t. It can be calculated using second equation of motion as follows :

s=ut+\dfrac{1}{2}gt^2

u is initial speed and it is 0

s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 29.4}{9.8}} \\\\t=2.44\ s

So, the stunt man is in the air for 2.44 seconds.

OLEGan [10]
The first sentence got me all psyched up to answer the question "What
horizontal force do the engines generate in order to accelerate it ?". 

But the actual question, in the second sentence, turned out to be
a completely different one.

When the plane levels off and continues on at a constant altitude, it's
not accelerating up or down, so the net vertical force on it is zero. 
The lift generated by the wings is exactly balancing the downward
force of gravity on the airplane.

Calculate the power provided by a 12-volt car battery with a rating of 350 amperes.
UNO [17]

The power provided by the car battery is 4200W or 4.2kW

<u>Explanation:</u>

Given:

Voltage, V = 12V

Current, I = 350A

Power, P = ?

According to Ohm's law:

Power = voltage X current

On substituting the value we get:

P = 12 X 350

P = 4200W

Therefore, the power provided by the car battery is 4200W or 4.2kW
