How Fast Was the Car Going When It Flew Off the Cliff?

AI Thread Summary
To determine the speed of the car when it flew off the cliff, first calculate the time it took to fall 32.7 meters using the formula for free fall, which is approximately 2.57 seconds. Given that the car traveled 153 meters horizontally during this time, the speed can be found by dividing the distance by the time. This results in a speed of about 59.6 m/s, which converts to approximately 214.56 km/h. The problem emphasizes the importance of understanding the relationship between horizontal distance, fall time, and constant speed in physics.

I have a HW problem that says:

A car drives horizontally off the edge of a cliff that is 32.7 m high. The police at the scene of the accident note that the point of impact is 153 m from the base of the cliff. How fast (in terms of km/h) was the car traveling when it drove off the cliff?

I've worked it out like 10 times. I only have one more chance to get it wrong on my online homework.

Someone please help... :cry:

How much time did the car have to fall?
If the car is traveling at a constnat speed horizontally and it traveled 153m, how fast was it traveling in that amount of time?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging 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...
