Loss of engine power/transmission 2001 chevy tahoe over 65 mph

Sound's as though a previous owner installed a speed governor so that the engine would not exceed the nationwide 55-65 mph speed limit average. This most likely was a company owned vehicle or owned by someone concerned about speeding ticket's or excessive speed by a teenage driver. It can be uninstalled by an experienced mechanic. Unless this poses a problem while driving on an interstate, you may wish to leave it as is.

If a car went from 0 to 100 km/h in 3.7 seconds, using the accelerationn formula how would I find the average acceleration?

Convert the speed from km / h to m/s.
Change in speed = (Final speed (in m/s) - initial speed (0))/ 3.7 s
The result is the average acceleration in m / s^2.
100 km /h = (100 000 m)/ (3600 s)= 27.7778 m/s

How to get the average of the velocity if motion is under constant acceleration

Take the example of a racing car as pictured in the animation above. It takes the vehicle 10 minutes(0.17 hours) to travel 23km, from start to finish.

Average speed = 23km / 0.17hrs = 135.29km/hr

Average velocity = 4km / 0.17hrs = 23.53km/hr

The average speed is 135.29km/hr but the velocity is only 23.53km/hr. The reason that velocity is lower, is that it can be positive and negative. Remember this from our earlier discussion on velocity? If not,click to refresh your memory. Since the velocity has negative and positive values some will cancel each other out, hence the lower value. Speed, however, can only be positive.

A monkey dropped a stone from a tower 19.6 metres high to a sea below the tower. After 2.057seconds he heard the sound of the stone. Find the speed of the sound ?

Assuming stone can be represented by a point mass and no air drag and the acceleration of gravity being 9.81 m/s^2 and initial stone velocity was zero we have
average speed being v(ave) = d/t = 19.6 / 2.057=9.528 m/s (meter per seconds)
and final speed be v(final) = a * t = 9.81 x 2.057 = 20.18 m/s

What is acceleration

In Physics acceleration is the rate of change of velocity over time. In one dimension, acceleration is the rate at which something speeds up or slows down.

In mechanics, for a body with constant mass, the acceleration of the body is proportional to the net force acting on it.

F=ma

where F is the resultant force acting on the body, m is the mas of the body, and a is its acceleration.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

When an object's velocity changes, it accelerates. Acceleration shows the change in velocity in a unit time. Velocity is measured in meters per second, m/s, so acceleration is measured in (m/s)/s, or m/s2, which can be both positive and negative.
