Answer:
The object will travel at a constant rate in along a straight line.
Explanation:
In the given situation, it is mentioned that there is no external force acting on the given object. Thus, it will retain its initial velocity along a straight path.
Okay so static friction is when the atoms lock themselves into place, which makes it 'hard' to push until you exceed its static force.
You can calculate the Fs by finding your normal force and multiplying it by your static friction force.
N = mg = (9.8)(42) = 411.6 N
Fs = NKs = (411.6)(0.75) = 308.7
a) the maximum force of static friction between her socks and the floor is 308.7 N
b) If you push Mazie with a force of 350 she will slide. She will accelerate if you keep pushing her with the constant force, but if you push her and let go the kinetic friction will eventually bring her to a stop.
c) So this is an interesting question, she's going at a speed of 0.6 m/s. Kinetic friction is pushing her back so theres a negative force which is the force of kinetic friction right. So its NKf = (411.6)(0.62) = 255.192.
Taking a bath, water at 40°C is required . calculate the mass of cold Water at 15°C which is to be added to 60 kg water at 100°C for bathing purpose
Answer:
2.25 seconds
Explanation:
Change in Acceleration = change in velocity / time interval
time interval = change in velocity / change in acceleration
= (9 - 0) / (0 - -4) = 9/4
= 2.25 seconds
