The answer is 2+ because I just know it’s easy
Answer:
Explanation:
The centripetal acceleration is expressed as;
a = v²/r
a is the acceleration = 50m/s²
v is the velocity = 10m/s
r is the radius
To get the radius
r = v²/a
r = 10²/50
r = 100/50
r = 2m
Hence its radius is 2m
D because if you are heavier and standing higher up then you will have greater potential energy than someone who weighs less and is standing at a lower height.
Answer:
P = 31.83 W
Explanation:
Our data are,
Magnitude of the force F = 26 N
Radius of the circular path r = 0.26 m
The angle between force and handle °
Time t = 2 s
We know that the formula to find the velocity is given by
Velocity
We know also that the formula to find the power is given by,
