Answer:
Workdone = 17482.36 Joules
Explanation:
Given the following data;
Force, F = 120 N
Angle, d = 28.0°
Distance, x = 165 m
To find the work done, we would use the following formula;
Workdone = FxCosd
Substituting into the formula, we have;
Workdone = 120*165*Cos(28)
Workdone = 19800 * 0.8830
Workdone = 17482.36 Joules
Answer:
9 N
Explanation:
The centripetal force F is F = mrω^2 = (mv^2)/r where m is mass, r is radius of the curve, ω is angular velocity and v is tangential velocity.
In this case, m = 0.5kg, r = 0.5m, v = 3m/s
So F = [0.5kg(3m/s)^2]/0.5m = 9kg-m/s^2 which is 9N
It would be rock by erosion bc the rocks erode to form a volcano
