AI Thread Summary
The kinetic energy of a baseball with a mass of 143 g and a velocity of < 22, 15, -12 > m/s is being calculated using the formula K = 1/2 mv^2. The user initially calculated the kinetic energy as < 34.6, 16.1, 10.3 > J but received feedback from WebAssign indicating the answer was incorrect. The discussion includes questions about the correct units and the calculation process, emphasizing the importance of converting grams to kilograms before applying the formula. Participants seek clarification on the correct method to arrive at the accurate kinetic energy values. Accurate calculations and unit conversions are crucial for determining the correct kinetic energy of the baseball.

A baseball of mass 143 g is thrown with a velocity of < 22, 15, -12 > m/s. What is the kinetic energy of the baseball?


Homework Equations


K=1/2mv^2



The Attempt at a Solution


i got < 34.6, 16.1, 10.3 > J
but webassign says i am wrong? what am i doing wrong?

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}...

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...
