To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
Answer: You can betterly understand what's around you and how it works
Answer:
(a) 
(b) 
(c) 
Explanation:
(a) According to Newton's second law, the acceleration of a body is directly proportional to the force exerted on it and inversely proportional to it's mass.
(b) According to Newton's third law, the force that the sled exerts on the girl is equal in magnitude but opposite in the direction of the force that the girl exerts on the sled:
(c) Using the kinematics equation:
For the girl, we have 
and 
. So:
For the sled, we have . So:
When they meet, the final positions are the same. So, equaling (1) and (2) and solving for t:
Now, we solve (1) for 
Answer:
The answer to your question is Equation vf = gt; vf = 29.6 m/s
Explanation:
Data
gravity = 3.7 m/s²
vf = ?
time = t = 8 s
Formula
vf = vo + gt
Initial speed = 0 m/s
To solve this problem we can use the equations of free fall and just substitute the data.
- Substitution
vf = 0 + (3.7)(8)
- Simplification
vf = 29.6 m/s
