Kinematics
Kinematics is the study of how a body moves. This includes linear motion, angular motion, and rotational motion.

An object is dropped on the earth After 1.5 s what is its speed in meters per second?
The object will be moving at 14.7 meters per second. 1.5 seconds X 9.8 meters per second squared(the gravitational constant). This assumes that the object's original velocity is zero.
Can a body in motion can never have zero average velocity?
While a body in motion cannot have zero average velocity, there are many examples where the average velocity - after selected intervals - is zero.
For example:
a pendulum, or any object under simple harmonic motion, after a complete number of cycles;
a rotating object (point on a wheel or hand of a clock) after a whole number of circuits.
It could either be an abbreviation of Master of Public Health, which is a degree awarded for people who study public health, or if you are referring to just mph, then it would represent miles per hour, which is a unit of measurement of speed.
States establish fines and penalties for traffic violations. There's no way to give a definite answer as it will depend upon the amount of actual fine, whether or not the state allows additional penalties for being a multiple offender (if that applies) and the amount set for court costs and other fees.
Along the rope. A vector arrow would be applied and point directly inward here in many physics books on mechanics.
As an object moves downhill some of the energy is?
Before it rolls downhill, it has gravitational potential energy. As it rolls downhill, part of this potential energy is converted into kinetic energy (including rotational energy); due to friction, this will soon be converted into waste energy, mainly heat.
How fast is 16 feet per second?
Pretty close to 10.91 miles per hour.
-- finish a marathon in 2hours 24minutes 12.2seconds (very impressive)
-- run a mile in 5minutes 30seconds (not too shabby)
-- 100 yard dash in 18.75 seconds (loafing)
-- cover a straight-line route to the moon in about 909 days (ridiculous)
What is the reaction force if a basketball was drop down from the empire state building?
The ball would bounce up very high
Is 45 kilometers per hour faster or slower than 26 miles per hour?
45 km per hour is slightly faster than 26 miles per hour (45km/h = 27.9617 mph).
Not at all. If it slows down or speeds up at any point, then it'll have different instantaneous
velocity at different points, and its average velocity for some section of the line can be yet
another different number.
Simple example:
A guy drives home from the office at a steady speed of 35 miles per hour.
On the way, he stops buy a soda.
His instantaneous velocity is zero during the stop, and 35 miles per hour
whenever he's moving.
His average velocity for the trip home is more than zero, and less than 35 miles per hour.
How many miles do you cover in 30 minute going 50 miles per hour?
Well, we know that in an hour, you'll go 50 miles. And 30 minutes is half an hour. So 50 divided by 2 is 25. That means that you will cover 25 miles in 30 minutes going 50 miles per hour.
How many miles per hour is 105 minutes?
Miles per hour is a unit of speed. Minutes are a unit of time. Without a unit of distance to convert, the two units are incompatible.
What is 12 miles per hour converted to yards per minute?
1 mile = 1760 yards
1 hours = 60 minutes
⇒ 12 miles per hour = 12 x 1760 yards per 60 minutes
= 12 x 1760 ÷ 60 yards per minute
= 352 yards per minute
