Answer:
Part a)
Part b)
Part c)
Explanation:
Velocity just before it strike the ground is given as
since there is no friction in horizontal direction so its speed in horizontal direction will remain same
Part a)
velocity in X direction
time taken by the skier to reach the ground is given as
now in the same time it will cover vertical distance
so magnitude of initial speed is given as
Part b)
Direction of velocity
Part c)
Now in order to find the height of the ramp we can find the vertical displacement
Answer:
please the answer below
Explanation:
(a) If we assume that our origin of coordinates is at the position of charge q1, we have that the potential in both points is
k=8.89*10^9
For both cases we have
(b) by replacing this values of r in the expression for V we obtain
hope this helps!!
