6) Ivan drives his truck 144 miles east on a straight highway for 45 minutes. How fast is he driving? HELPPPN PL HOW DO I TYPE THIS IN UNITS

3.2 miles per minute or 192 miles per hour

Explanation:

rate = distance divided by time, so 144/45 = 3.2

for every 1 hour there are 60 minutes. so 3.2* 60 is 192

not sure what you meant by typing in unit though, miles per minute is mpm.

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.
