Answer:
t = 0.55[sg]; v = 0.9[m/s]
Explanation:
In order to solve this problem we must establish the initial conditions with which we can work.
y = initial elevation = - 1.5 [m]
x = landing distance = 0.5 [m]
We set "y" with a negative value, as this height is below the table level.
in the following equation (vy)o is equal to zero because there is no velocity in the y component.
therefore:
Now we can find the initial velocity, It is important to note that the initial velocity has velocity components only in the x-axis.
Answer:
Explanation:
Here by energy equivalence we can say that energy given by the metal piece is same as the energy absorbed by the water
so here we have
here we know that
