Ignoring resistance, the ball will travel upwards until it's velocity is 0 m/s. So we'll first calculate how many seconds that takes.
7.2 m/s / 9.81 m/s^2 = 0.77945 s
The distance traveled is given by the formula d = 1/2 AT^2, so substitute the known value for A and T, giving
d = 1/2 A T^2
d = 1/2 9.81 m/s^2 (0.77945 s)^2
d = 4.905 m/s^2 0.607542 s^2
d = 2.979995 m
So the volleyball will travel 2.979995 meters straight up from the point upon which it was launched. So we need to add the 0.80 meters initial height.
d = 2.979995 m + 0.8 m = 3.779995 m
Rounding to 2 decimal places gives us 3.78 m</span>
Answer: the water level would rise since the pebble displaces minimal water compared to the boat.
Explanation:..........
The Rio Grande was the major route prior to the Panama Canal.
Answer: 1.8m
Explanation:
Using the principle of moment to solve the question which states that the sum of clockwise moment is equal to the sum of anticlockwise moments.
The boy moves in the clockwise direction towards the pivot while the girl moves in the anticlockwise direction towards the pivot.
Since moment = force × perpendicular distance
CW moments = 60×1.5 = 90Nm
ACW moments = 50×x = 50x
Equating both moments to get 'x'
90 = 50x
x =9/5
x = 1.8m
This shows that the girl must sit 1.8m from the other side for equilibrium.:
