Answer:

Dummies deceleration is 11m/s²

Explanation:

According to Newton's second law, the relationship between the force applied to an object, its mass, and the acceleration (or deceleration) caused, is given by:

F=ma

Solving for acceleration:

a=\frac{F}{m}

If we plug in the vales (taking into account the negative sign of the force, as its directed backwards):

a=\frac{-825N}{75kg}=-11m/s^2

a=-11m/s^2

Deceleration is simply the magnitude of negative acceleration. Therefore, dummies deceleration is 11m/s²

Use Force=Mass x Acceleration (newtons second law states force is directly proportional to the acceleration) so you can say that the force is negative and solve for Acceleration.

What is the deceleration of a bicycle that goes from 40m/s to 20m/s in 5 seconds
Alex Ar [27]

Answer:

-4 m/s^2

Explanation:

The acceleration of the bycicle is given by:

a=\frac{v-u}{t}

where

v = 20 m/s is the final velocity of the bike

u = 40 m/s is the initial velocity

t = 5 s is the time interval

Substituting numbers, we find

a=\frac{20 m/s-40 m/s}{5s}=-4 m/s^2

and the acceleration is negative, which means that the bycicle is slowing down.

Are there conditions under which the incident light ray undergoes reflection but not transmission at the boundary? if so, then w
Luden [163]

Total internal reflection causes light to be completely reflected across the  boundary between the two media but not transmitted.

<h3>What is total internal reflection?</h3>

The term total internal reflection occurs when light is moving from a denser to a less dense medium such as from glass to air. This phenomenon occurs at the interface between the two media.

There are two conditions necessary for total internal reflection and they are;

1) Light must travel from a denser to a less dense medium

2) The angle of incidence in the denser medium must be greater than the critical angle.

Total internal reflection causes light to be completely reflected across the  boundary between the two media but not transmitted.

How are metals identified i the periodic table??
zaharov [31]

Answer:

okay here is a thing I learned when I was younger in my middle school:

Explanation:

my teacher would tell me that metals are considered a weak metals are on the left side and the good metals are located on the right side because the only way I remembered was the right means it is really strong and the left is weak and not that supportive. but I think that's how I still think it is or other people may have their own opinions. but hope this helped out with your question!
