Answer:
Explanation:
Normal force - should be the reaction from the surface it's on - nullifies the weight of the object. At this point the only force is of from whoever is pushing the square and the friction, towards the right. At this point we divide the force by the mass of the object to obtain an acceleration of
Answer:
Explanation:
As we know that the centripetal force is given as
now we will have to find the rate of change in force with respect to its radial distance
so we have
so we have
m = 1000 kg
v = 13.89 m/s
r = 200 m
now we have
the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person,
