Answer:
32.925 m.
Explanation:
The formula of centripetal acceleration is
a = v²/r ............... Equation 1
Where a = centripetal acceleration, v = linear velocity, r = radius.
make r the subject of the equation.
r = a/v²............. Equation 2
Given: v = 22 m/s,
a = 1.5 times free fall acceleration
Note: Free fall = 9.8 m/s²
Therefore, a = 1.5×9.8 = 14.7 m/s²
Substitute into equation 2
r = 22²/14.7
r = 484/14.7
r = 32.925 m.
Hence the radius of the turn = 32.925 m.
2.5 percent is fresh and only one present is easy to get.
Answer:
Sometimes actions have ulterior motives.
Explanation:
you never know what actions could do something else you can never be to positive about what will happen, when you are doing something uncomfortable with someone you don't really trust.
It would weigh less bc the higher you are the less gravity there is.
Answer:
361.8 J
Explanation:
= Pulling force applied on the sled by the child = 55 N
= Angle between the direction of pulling force and displacement = 20 deg
= Displacement of the system = 7.0 m
= Work done by the child's pulling force
We know that work done is given as
