How Fast Does a Bowling Ball Travel When It Falls Off a Table?

AI Thread Summary
To determine the velocity of a bowling ball as it falls off a 1.0 m high table, the horizontal velocity is given as 10 m/s, while the vertical velocity must be calculated using the acceleration due to gravity at 9.8 m/s². The time taken to fall can be calculated using the formula for free fall, resulting in a vertical velocity of approximately 4.43 m/s upon reaching the floor. The overall velocity can then be found by combining the horizontal and vertical components using the Pythagorean theorem, yielding a magnitude of about 11.18 m/s. The direction of the velocity can be determined using the arctangent of the vertical to horizontal velocity ratio.

Bowling ball and table!

Can anyone please help me figure this one out;

A bowling ball of mass 7.5kg traveling at 10m/s rolls off a horizontal table 1.0 m high. Calculate the velocity of the ball as it reaches the floor, ignoring air resistance and having an acceleration due to gravity of 9.8m/s.

They gave you the horizontal component of velocity. They want you to find the vertical component and then combine the 2 like Pythagoras would to yield the answer for the magnitude of the |velocity| vector. Now they may also want you to give the direction. (That would be tan-1 of the ratio of the 2.)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
