Which law of motion is this an example of?

Answer:Newton’s law also states that larger bodies with heavier masses exert more gravitational pull, which is why those who walked on the much smaller moon experienced a sense of weightlessness, as it had a smaller gravitational pull. To help explain his theories of gravity and motion, Newton helped create a new, specialized form of mathematics.

A 15 kg cart is pushed on a frictionless surface from rest horizontally by a 30 N force. What is the cart's acceleration?

Rainbow [258]

Answer:

<em>a. The cart's acceleration is 2 m/s^2</em>

<em>b. The cart will travel 100 m</em>

<em>c. The speed is 20 m/s</em>

Explanation:

a. The acceleration of the cart can be calculated using Newton's second law:

F = m.a

Solving for a:

$\displaystyle a=\frac{F}{m}$

The cart has a mass of m=15 Kg and is applied a net force of F=30 N, thus:

$\displaystyle a=\frac{30}{15}$

$a=2\ m/s^2$

b.

Now we use kinematics to find the distance and speed:

$\displaystyle x = v_o.t+\frac{at^2}{2}$

The cart starts from rest (vo=0). The distance traveled in t=10 seconds is:

$\displaystyle x = 0*10+\frac{2*10^2}{2}$

$x = 100\ m$

The cart will travel 100 m

c.

The final speed is calculated by:

$v_f=0+2*10=20\ m/s$

The speed is 20 m/s

When a 100-N force acts horizontally on an 8.0-kg chair, the chair moves at a constant speed across the level floor. Which state

TiliK225 [7]

Answer:

The applied force is greater than the frictional force.

Explanation:

the chair moves at <u>a constant speed</u><u> </u><u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>not</u><u> </u><u>A</u><u> </u><u>or</u><u> </u><u>C</u><u>.</u>

if there is no friction then the chair <u>would accelerate and it would not be at a constant speed</u><u>.</u>

hence, the only possible answer is B.
