Power

AI Thread Summary

To calculate the average power delivered by a 1300 kg sports car accelerating to 95 km/h in 7.3 seconds, the relevant equations include acceleration (a = Δv/Δt), force (F = ma), work (w = F*d), and power (p = w/t). The car's acceleration can be determined by converting 95 km/h to meters per second and dividing by the time. Using the mass and calculated acceleration, the force can be found, followed by calculating the distance traveled during acceleration. Finally, the work done can be divided by the time to find the average power, which should be expressed with two significant figures.

A 1300 Kg sports car accelerates from rest to 95 km/h in 7.3 sec..

What is the average power delivered by the engine?
express answer using 2 significant figures.

cannot figure this out.. any help would be great!
thanks,
Brandon

the relavent equations?

a = Δv/Δt

F = ma

w = f*d

p = w/t

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
