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.

No. You have the units wrong.
Example with numbers:
When you multiply (1/9) by 2, you get 2/9 .
With units:
When you multiply (m/s) by (kg), you get (kg-m/s).

Answer:
Correct answer : v = 50 m/s
Explanation:
The movement described is a free fall with no initial velocity and we will use the following formula:
v = g · t we take that g = 10 m/s²
v = 10 m/s²· 5 s = 50 m/s
v = 50 m/s
