Answer:
Time, t = 2 seconds
Explanation:
Given the following data;
Mass, m = 50 kg
Initial velocity, u = 0 m/s (since it's starting from rest).
Final velocity, v = 8 m/s
Force, F = 200 N
To find the time, we would use the following formula;
Making time, t the subject of formula, we have;
Substituting into the formula, we have;
Time, t = 2 seconds
Answer:
The power will be "250 watt". A further explanation is given below.
Explanation:
The given values are:
Force,
F = 50 N
Displacement,
d = 20 m
Time,
t = 2.0 seconds
Whenever the block is pulled, the angle will be "0" i.e., Cos0° = 1
Now,
The work will be:
= 
On substituting the given values, we get
= 
= 
= 
Now,
The Power will be:
= 
= 
= 
The answer is E I think.. don’t trust me 100%
Answer:
The answer to your question is a = 1.3 m/s²
Explanation:
Centripetal acceleration is the motion of a body that transverse a circular path.
Data
mass = 7 kg
radius = r = 1.3 m
angular rate = w = 1.0 rev/s
centripetal acceleration = a = ?
Formula
a = rw²
Substitution
a = (1.3)(1)²
Simplification and result
a = 1.3 m/s²
When you say atmospheric pressure it is a standard on all places on earth. The value of standard atmospheric pressure is 1 Bar approximately or 14.7 lb per square inch. This pressure is an attribute of free molecules on the air which is not bound the accumulation of the pressure of this in average is the atmospheric pressure.
