Question

Two vehicles get into an accident. The first vehicle is traveling east and runs into a stopped vehicle (pointed into the north direction). the First vehicle has 19.5 m of skid marks before impacting the second vehicle on its drivers side. The two vehicles stick together and have skid marks of 8.75m before coming to a stop together. The first vehcile's mass is 3256 kg and the second vehicles masss is 1100kg. The posted speed limit is 45mph. Force vertical = 86.5 N and force horizontal = 74.3 N. necessary for determining coefficient of friction.

What is the coefficient of friction ?

What is the initial speed of the first vehicle and how did you determine it?

Explanation / Answer

The posted speed limit is 45mph. ( What is this velocity ? ?)

Force vertical = 86.5 N and force horizontal = 74.3 N. ( What are these forces ? ?)
