AI Thread Summary
In a scenario involving two identical vehicles on a damp road, one stationary with brakes applied and the other traveling at 15 mph, the forces experienced by the occupants will differ due to the motion of the second vehicle. Newton's laws of motion apply, indicating that the moving vehicle will exert greater forces upon impact compared to the stationary one. The damp road surface may also affect braking efficiency and impact dynamics. Consequently, injuries sustained by the occupants are likely to be unequal, with the moving vehicle's occupants facing higher risks. Understanding the frame of reference related to the center of mass can aid in analyzing the situation further.

Homework Statement


Two identical vehicles 1 vehicle stationary and with brakes applied other vehicle traveling at 15mph. Road surface of good tarmacadam but damp after rain. Would occupants of both vehicle experience the same forces and would the injuries sustained be equal?

Homework Equations



Newtons laws of motion

The Attempt at a Solution



So long ago since I worked this at out college (50 years!) I can't remember formulae and method. Any help would be appreciated.

Choose a frame of reference connected with the center of mass of the 2 objects to discribe distance and velocity. Does this help?
 

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}...
