Hi there!

Since you are just trying to find the vertical acceleration and not the horizontal acceleration, angle and velocity do not come into play in this problem. The downward pull of gravity has a vertical acceleration of 9.8 m/s/s, which would be your answer.

When you're dealing with projectile problems, you have two dimensions: an x (horizontal) dimension and a y (vertical) dimension. The only force that will be acting upon a projectile in the air is the force of gravity, which points down in the y/vertical dimension.

Gravity causes a downward vertical acceleration of -9.8 \:m/ s^{2}.
The velocity and angle do not affect the vertical acceleration.

A student has a mass (including clothes and shoes) of 65.0 kg. She drinks a 12 oz. can of soda, with a nutritional energy conten
Stella [2.4K]

She can climb 0.92 m without losing weight.

<u>Explanation</u>:

Gravitational potential energy is the energy consisting of the product of mass, gravity and height.

1 cal = 4184 J

140 cal = 585760 J

Energy = 585760 J,  m = 65.0 kg = 65000 g,   Efficiency = 20 %

                                 GPE = mgh

where m represents the mass

          g represents the gravity,

           h represents the height.

                             585760 = 65000 \times 9.8 \times h

                                        h = 0.92 m.

If Phoenix, Arizona, experiences a cool, wet day in June, does that mean the regions climate is changing?
jenyasd209 [6]
It doesn't mean that the climate is changing, it is probably just the morning dew.

An automobile moves on a level horizontal road in a circle of radius 30 m. The coefficient of
blondinia [14]

Answer:

v = 12.12 m/s      

Explanation:

It is given that,

Radius of circle, r = 30 m

The coefficient friction between tires and road is 0.5,

The centripetal force is balanced by the force of friction such that,

v = 12.12 m/s

So, the maximum speed with which this car can round this curve is 12.12 m/s. Hence, this is the required solution.

If you hold your hand over a pot of boiling water, it feels hot. Explain how the boiling water is transforming heat to your hand
MakcuM [25]

I don't no if this helps but the body heat from your hand causes the liquid to boil, which in turn makes the liquid evaporate, turning it to gas. The expanding gas pushes the liquid upwards and when you release your hand, equilibrium is re-established.
