Answer:
The answer to your question is 1.35 Watts
Explanation:
Data
Work = W = 5 J
time = t = 3.7 s
Power = P = ?
Formula
Power is a rate in which work is done or energy is transferred over time
P = 
Substitution

Result
P = 1.35 W
Answer:
T = 8.55 N
Explanation:
When string makes an angle 40 degree with the vertical then it will have two forces on it
1) gravitational force (mg)
2) Tension force in string (T)
now we know that net force towards the center of the path is known as centripetal force and it is given as





The answer to this would be C
The formula for this equation is:
change in velocity/time taken = acceleration
7/3 = 2.3...
so the answer is 2.3 m/s
(I am not positive with the answer but I do know that is the formula for the equation)

Answer:
Acceleration, a=6.66\ m/s^2
Explanation:
Given that,
Force acting on the object, F = 500 N
Mass of the object, m = 75 kg
We need to find the acceleration of the object. The force acting on the object is given by :
a=\dfrac{F}{m}
a=\dfrac{500\ N}{75\ kg}
a=6.66\ m/s^2
So, the acceleration of the object is 6.66\ m/s^2. Hence, this is the required solution.
