Answer:
a.After second Mr Comer's speed
b.Distance travelled by Mr.Comer in seconds
Explanation:
a. Lets recall our first equation of motion
Now we know that ,
and
Plugging the values we have.
Then Mr.Comer's speed after sec
b.
Lets find the distance and recall our third equation of motion.
So distance covered.
Dividing both sides with 2a we have.
Plugging the values.
So Mr.Comer will travel a distance of .
The work that need to do is 66.24 J.
<h3>Explanation :</h3>Hello guys, before we can count how much the work that needed to pull the toy, we should know how formula to count it first. Because the movement is with the angle, so the formula is :
If :
- W = work (J)
- F = force (N)
- s = shift (m)
- θ = elevation angle (°)
We know that :
- x = the horizontal shift = 9,2 m
- θ = elevation angle = 15°
W = work = ... J
So, the work that need to do is 66.24 J.
