The first thing you should do for this case is to find the horizontal and vertical components of the forces acting on the body.
We have then:
Horizontal = 9-9.2cos (58) = 4.124742769 N.
Vertical = 9.2sin (58) = 7.802042485 N
Then, the resulting net force is:
F = √ ((4.124742769) ^ 2 + (7.802042485) ^ 2) = 8.825268826 N
Then by definition:
F = m * a
Clearing the acceleration:
a = F / m
a = (8.825268826) / (3.0) = 2.941756275 m / s ^ 2
answer:
The magnitude of the body's acceleration is
2.941756275 m / s ^ 2
Mass and energy are equivalent. I'm doing the same test right now.
Answer:
object B of 30 kg
Explanation:
an example be..let object B is earth and object A is moon ....the gravitational force of earth is greater than moon because the higher the mass the more the gravitational force towards it.
Answer:
The rate of work is 360 W
Explanation:
Given:
Speed of block 
Upward acceleration of block 
Mass of block 
kg
First Find the force act on block due to gravity
Where 
N
For finding at what rate motor doing work when it is pulling the block upward,
W
Therefore, the rate of work is 360 W
