1) when a Car Moves; its Wheels exhibit Both Rotational and Rectilinear Motion

2) When Earth rotates Around the sun it is executing Periodic motion through revolving around the sun; at the same time it is executing Rotatory motion by rotating on its own axis.

Hope it helps...

Answer:

Change in translational KE is given as

$\Delta k = FL + (4m + M)gh - \frac{1}{4}MR^2\omega^2 - 2mb^2\omega^2$

Explanation:

As we know by work energy theorem that work done by all forces is equal to the change in kinetic energy of the system

So here we know that there are two forces acting on the system

So work done by the system of this force is equal to the change in kinetic energy

So we have

$W = FL + (4m + M)gh$

So we have

$FL + (4m + M)gh = \Delta K + \frac{1}{2}(\frac{1}{2}MR^2 + 4mb^2)\omega^2$

so we have

$\Delta k = FL + (4m + M)gh - \frac{1}{4}MR^2\omega^2 - 2mb^2\omega^2$

The height above the ground of a stone thrown upwards is given by s(t), where t is measured in seconds. After 1secondnothing,t

Answer:

v = 14 ft/s

Explanation:

By definition, the average velocity, is just the rate of change of the position, with respect to time, which can be written as follows:

$v_{avg} = \frac{\Delta x}{\Delta t} = \frac{x_{f}-x_{o}}{t_{f} - t_{o}} (1)$

Defining the vertical position as the y-coordinate, with the origin at ground level, and the upward direction as positive, we can write (1) as follows:

$v_{avg} = \frac{\Delta y}{\Delta t} = \frac{y_{f}-y_{o}}{t_{f} - t_{o}} (2)$

where yf = 54 ft, y₀ = 47 ft, tif = 1.5 s, t₀ = 1s.
Replacing in (2) we get:

$v_{avg} = \frac{\Delta y}{\Delta t} = \frac{y_{f}-y_{o}}{t_{f} - t_{o}} = \frac{7ft}{0.5s} = 14 ft/s (3)$

People living at Earth’s equator are traveling at a constant speed of about 1,670 km/h as Earth spins on its axis. What are thes

Vlada [557]

The people living around the equator experience acceleration. Acceleration is the change in speed or/and direction. When on a rotating body, the speed does not change it is only the direction that changes as it rotates.When on a rotating body you do not have to change speed but only direction. In a normal situation when you are traveling on a circle you will never have a straight line.
