How Do Physics Principles Explain a Car's Trajectory and Collision Dynamics?

AI Thread Summary
The discussion focuses on solving a physics problem involving a car's trajectory and collision dynamics after it falls from a cliff. The car, traveling at 45 m/s, will hit the ground at a certain distance from the cliff, which can be calculated using projectile motion equations. After hitting the ground, the car decelerates due to friction, and the deceleration can be determined using the coefficient of friction provided. Additionally, the problem involves an elastic collision with a stationary Honda Civic, where the final velocity of the Civic can be found using conservation of momentum principles. Participants are encouraged to apply relevant physics equations to arrive at the solutions.

Velocity, displacement?
Please help me to solve this! I have no idea!

The brakes of a car failed and the car travels at a constant velocity of 45 m/s off a 27 m cliff.

A) How far from the cliff does the car hit the ground?

B)When it hits the ground, it skids off 13 m/s with a coefficient of friction of 0.55. What's the deceleration of the car?

C) The car travels 5 m when it crashes into a stationary 650 kg Honda Civic. The collision is elastic. The velocity of the original car is 2 m/s after the collision. What is the velocity of the Honda Civic after the crash?

Please give me tips on how to solve this! i will give 10 points to the best answer!]

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...
