To determine the height of the object given the time, we simply use the given relation between height and time in the problem statement. It is given as:
h = -16t^2 + 127t
We substitute 55 seconds to t and obtain,
h = -16(55)^2 + 127(55)
h = - 41415
Answer:
At an angle of
Explanation:
Assume the river flows from East to West so for the swimmer to cross across it, assume he crosses it from West to East.
The resultant speed will be given by
Increasing the masses of the objects and decreasing the distance between the objects
This would be the definition of gravitational force, I believe. The force of attraction between 2 objects based on the mass of the objects.
