AI Thread Summary
The problem involves a bowling ball rolling off a table at 15 m/s and landing 45 m away. To find the time of fall, the equation t = d/v yields t = 3 seconds. For the height of the table, the formula Dy = (1/2)gt^2 is used, with g as 9.8 m/s² or 10 m/s². Substituting the values, the height can be calculated based on the time of fall. The discussion emphasizes applying kinematic equations to solve for both time and height.

Homework Statement


A bowling ball rolls off a giant's table at a speed of 15 m/s and lands 45 m from the base of the table.

(a) for how many seconds is the ball falling?
(b) how high is the table?

s=15 m/s
d=45 m
v(i)=0
v(f)=15 m/s ?
t=?


Homework Equations



v=d/t
t=d/v
d=vt

The Attempt at a Solution



t=45 m / 15m/s

(a) t=3 s

(b) i honestly have no clue

Use
Dy = (1/2)*g*t^2

where g is acceleration due to gravity. Use 9.8m/s^2 or 10m/s^2 depending on what your course uses.
 

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}...
