Answer: 5.8kg
Explanation:
F - mg sinΦ = ma
Given that
M=?
g= 9.8
Φ= 30
a= 2
F= 40 then
40 - 9.8 * m * sin 30 = 2 * m
40 = 2 * m + 9.8 * m * sin 30
40 = (2 + 9.8 * sin 30) m
m = 40 / (2 + 9.8 * 0.5)
m = 40 / (2 + 4.9)
m = 40 / 6.9
m = 5.797kg
m = 5.8kg
Answer:
False
Explanation:
This is due to the gravitational pull, since the moon does not have the same force or gravity like Earth, your weight would change.

Answer:
If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
Explanation:
Answer:
More work done with less power
The increase in gravitational energy is the same as the height which is a function of gravitational energy is the same in both cases
Explanation:
Climbing the mountain in zigzag pattern is easier because
1. The time it takes to climb increases so that the required power or rate of doing work decreases
2. Climbing in zigzag pattern affords the use of leverages by the sides
3. Similar mechanical power gain and efficiency from using a drive screw instead of a nail to fasten items together can be achieved
The increase in gravitational energy is the same gravitational energy ~ mass × gravity ×height
The average velocity is -4.17 m/s
Explanation:
The average velocity of a body is given by:
where
d is the displacement of the body
t is the time elapsed
For the student in this problem, we have:
Initial position:
Final position:
So the displacement is
The time elapsed is
t = 60 s
Therefore, the average velocity is
Where the negative sign means the student is moving towards the origin.
