HELP IM TIMED. ILL MARK BRAINLIEST PLSSSSSS.
Alex17521 [72]

Answer:

According to Newton's Second Law of Motion :    

Where,

F = Force Applied

m = Mass of the object

a = Acceleration

Now, we will use this law to solve this question.

Given :

Acceleration or a = 15.3 m/s²

Force = 44 N

Mass = ?

Substitute, the given values in the formula.

F = ma

⇒ m = F/a

   m = 44/15.3

<u>m = 2.9 kg</u>

How does the angle of launch affect the kinetic energy of a rubber band?​
Lady_Fox [76]

Answer:

The angle of launch of the rubber band affects the initial velocity. The more the rubber band is stretched the more force it applies to return to equilibrium and the more kinetic energy that results in.

Contact [7]

Answer:

v_{i}=10.10 m/s

Explanation:

The equation of the position is:

y=y_{i}+v_{i}t-0.5gt^{2}

Where:

v(i) is the initial velocity

The initial position y(i) will be zero and the final position y = 3.60 m.

So, we just need to solve this equation for v(i).

v_{i}=\frac{y+0.5gt^{2}}{t}

v_{i}=\frac{3.6+0.5*9.81*1.6^{2}}{1.6}

v_{i}=10.10 m/s

Therefore, the initial velocity is 10.10 m/s upwards.

I hope it helps you!

A train has a constant velocity of 2 m/s east. What is the magnitude of the horizontal acceleration of the train? A. −2 m/s² B.
Serga [27]

"Acceleration" is the rate at which velocity changes.
So "constant velocity" is a very good definition of "no acceleration".

Choice-B is the correct one.
