What is the maximum reaction time to avoid hitting a deer on the road?

AI Thread Summary
To avoid hitting a deer while driving at 56 km/h with a deer 65 m ahead, the driver must calculate the maximum reaction time before applying brakes with an acceleration of -3.0 m/s². The discussion emphasizes the importance of demonstrating prior effort in solving the kinematics problem, as per forum rules. Participants are encouraged to engage with the problem-solving process rather than simply seeking answers. Understanding the physics involved is crucial for determining safe driving practices. The focus remains on calculating the reaction time necessary to prevent a collision.

a car is moving at 56km/h when a deer jumps onto the road 65m ahead. after a reaction time of t seconds, the driver applies the brakes to produce an acceleration of -3.0m/s^2. what is the maximum reaction time allowed if the car is to avoid hitting the deer?

It may be "fun" to solve that kinematics problem, but why exactly did you post here? If you have any doubts or want help to solve the problem, you have to show some previous effort on trying to solve the exercise (forum rule).
 

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...
