An object in motion will stay in motion until a force is acted upon it, and object at rest will stay at rest until a force is acted upon it.

Answer:

Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.

A gyroscope flywheel of radius 3.25 cm is accelerated from rest at 11.6 rad/s2 until its angular speed is 1820 rev/min. (a) What

kati45 [8]

Explanation:

The given data is as follows.

radius (r) = 3.25 cm, $\alpha = 11.6 rad/s^{2}$

Now, we will calculate the tangential acceleration as follows.

$a_{tangential} = \alpha \times r$

Putting the given values into the above formula as follows.

$a_{tangential} = \alpha \times r$

= $11.6 rad/s^{2} \times 3.25 cm$

= 37.7 $rad cm/s^{2}$

Thus, we can conclude that the tangential acceleration of a point on the rim of the flywheel during this spin-up process is 37.7 $rad cm/s^{2}$ .

What do you mean by MA of a lever is 3 , VR of a lever is 4 and efficiency of a machine is 60%

Montano1993 [528]

Explanation:V.R of a lever is 3 means effort distance of the lever is 3 times more than the effort distance of the load. ... Efficiency of a lever is 60% means 40% of the energy is wasted due to friction as no machine is Friction less.

A car of mass 1689-kg collides head-on with a parked truck of mass 2000 kg. Spring mounted bumpers ensure that the collision is

Blababa [14]

Answer:

The initial velocity of the car is V1= 5.58 m/s = 20.12 km/h

Explanation:

m1= 1689 kg

v1= ?

m2= 2000kg

v2= 17 km/h = 4.72 m/s

by the conservation of quantity of movement :

m1*v1 = m2*v2

v1= m2*v2 / m1

v1= 5.58 m/s = 20.12 km/h
