Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
Explanation:
Answer:
The value of 2.2 radians in degree is 126.11°.
Explanation:
Given that,
Angle = 2.2 radians
We need to calculate the value in degrees
We know that,



Hence, The value of 2.2 radians in degree is 126.11°.
Answer:
a) 
b) 
Explanation:
From the exercise we have <em><u>initial height and final X position</u></em>


a) From the concept of <u>free falling objects</u> we have that

Since the car runs off the edge of the table, that means the car is moving in x direction with
and at the end of the motion 

<em><u>Solving for t </u></em>
t=± 0.6072 s
Since the time can not be negative, the answer is t=0.6072 s
b) To find the <u>horizontal velocity</u> of the car, we need to use the time that we just calculate


The minimum speed needed a non-propelled object to escape from the gravitational influence of a massive body, that is to achieve an infinite distance from it. I think
