This describes projectile motion while neglecting any outside forces other than gravity

I believe the answer is projectile
As the object reach its maximum height after it thrown, its speed will falls into 0. But due to the gravity force, the speed of the object will start to accelerate again after it came down until it hit another medium.
Example of projectiles: a thrown baseball, a catapult shot.

If the distance between two asteroids is halved, the gravitational force they exert on each other will

mamaluj [8]

Answer:

e) Be four times greater

Explanation:

Here we have to use Newton's gravitational law that relates the gravitational force between two objects with their masses ( $m_{1}$ & $m_{2}$ ) and the distance between them ( $r$ ) in the next way:

$F=G\frac{m_{1}m_{2}}{r^{2}}$ (2)

Now if distance between asteroids is halved:

$F_{2}=G\frac{m_{1}m_{2}}{(\frac{r}{2})^{2}}$

$F_{2}=G\frac{m_{1}m_{2}}{\frac{r^{2}}{4}}$

$F_{2}=G\frac{4m_{1}m_{2}}{r^{2}}=4G\frac{m_{1}m_{2}}{r^{2}}$

Note that $G\frac{m_{1}m_{2}}{r^{2}}$ because (1) is F so:

$F_{2}=4F$

It's four times greater!

How long will it take a cyclist to accelerate to 12 m/s starting from rest if he rides with an average acceleration of 1.2 m/s^2

igor_vitrenko [27]

Answer:

<em>The cyclist takes 10 seconds to accelerate to 12 m/s.</em>

Explanation:

<u>Constant Acceleration Motion</u>

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

$v_f=v_o+at$

Solving for t:

$\displaystyle t=\frac{v_f-v_o}{a}$

The cyclist starts from rest (vo=0) and moves at vf=12 m/s with an acceleration $a=1.2\ m/s^2$ .

Calculate the time:

$\displaystyle t=\frac{12-0}{1.2}$

$\displaystyle t=\frac{12}{1.2}$

$\boxed{t=10\ sec}$

The cyclist takes 10 seconds to accelerate to 12 m/s.
