Answer:
130°
Step-by-step explanation:
Line AD = 180°
Angle BED = 50°
180°-50°=130°
Answer:
Step-by-step explanation:
Since the triangle is inscribed in a semicircle, then angle x is a right angle. That means that angle y is 180 - 90 - 31, which is 59.
- Force=0.02N=F
- Acceleration=a=8m/s^2
- Mass=m
According to Newton's second law
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
