Answer:

Final velocity of the car will be -9.28 m/sec        

Explanation:

We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec

Acceleration of the car a=1.6m/sec^2 in negative direction so acceleration will be a=-1.6m/sec^2

From first equation of motion we know that

v = u+at

So v=0+(-1.6)\times 5.8=-9.28m/sec

So final velocity will be -9.28 m/sec

A ladybug has a mass of 0.01 g and a velocity of 0.6 m/s. What is his momentum?
Alex

0.000006‬kgm/s

Explanation:

Given parameters:

Mass = 0.01g

Velocity = 0.6m/s

Unknown:

Momentum = ?

Solution:

The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .

  Momentum = mass x velocity

The unit is in kgm/s

 We need to convert the mass to kilograms:

       1000g = 1kg

      0.01g = x kg ;  0.00001‬kg

Input the parameter:  

     Momentum = 0.00001 x 0.6 = 0.000006‬kgm/s

ccording to the law of inertia, if you see an object in motion slowing down, what can you conclude? a. That there must be some e
ivanzaharov [21]

Answer:

a)

Explanation:

Newton's First law (aka law of inertia) says that any object, not subject to an external influence, must be keep in its present motion status (at rest or moving at constant speed along a straight line) forever.

So, if we see an object in motion slowing down, there must be an external infuence acting on it, that makes it slow down, like a friction force, for instance.
