You begin sliding down a 15° ski slope. Ignoring friction and air resistance, how fast will you be moving after 10 s? Please express your answer in meters per second (m/s). Thank you in advance!

25.4 m/s.

Explanation:

0+2.54×10=25.4m/s

Taking the x-coordinate to be parallel, and moving down the ramp or in other words, moving to the right will be somewhat positive.

Solution:

So...

Use the formula [ fv = iv + at ] when iv = 0, a = 2.54, and t = 10

Therefore, the answer is 25.4m/s

Best of Luck!

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
