When examining the scene of an accident involving two cars, investigators measure 73-m-long skid marks of one of the cars, which nearly came to a stop before colliding. The coefficient of kinetic friction between rubber and the pavement is about 0.90. Estimate the initial speed of that car assuming a level road.

1. The block shown in (Figure 1) has mass m = 7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ = 24.5 ∘ to the horizontal. a. Determine the acceleration of the block as it slides down the plane. Express your answer to three significant figures and include the appropriate units. b. If the block starts from rest 19.0 m up the plane from its base, what will be the block's speed when it...

Police Report: There were two individuals involved in the accident. No other passengers were present and no other vehicles were involved. There was a truck of mass 1,936 kg traveling Southbound on H and a compact car of mass 1,077 kg travelling Northbound on HWY 26. A bystander claims to have watched the vehicles collide and slide Southbound off the road into a tall grassy ditch. The grass was determined to have a coeficient of friction of 0.6, while the...

Consider the following
two-caraccident: Two cars of equal mass collide at an intersection. Driver E was traveling
eastward, anddriver N, northward. After the collision, the two cars
remainjoined together and slide, with locked wheels, before coming
torest. Police on the scene measure the length of the skid marks to be 9 meters. The coefficient
offriction between the locked wheels and the road is equal to
0.9.
Each driver claims that hisspeed
was less than 14 meters per second (50 mph)....
