What is the power of a car traveling at 30. m/s with a force of 1000. N?

AI Thread Summary

To calculate the power exerted by a force of 1000 N on a car traveling at 30 m/s, the formula for power, which is the product of force and velocity, is used. Power is defined as the rate of doing work, expressed in watts (J/s). The calculation involves multiplying the force (1000 N) by the speed (30 m/s), resulting in a power output of 30,000 watts or 30 kW. The discussion confirms that both force and speed are in the same direction and treats all values as positive. Understanding these concepts is essential for solving similar physics problems.

I got it. Since a Joule is a N*m, and Power is a N*m/s; I just multiple the 1000N by 3m/s to get the power. Thanks brain!

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...
