WILL MARK BRAINLIEST A driver of a car traveling at 16.1 m/s ap-
plies the brakes, causing a uniform deceleration of 2.8 m/s

- How long does it take the car to accelerate
to a final speed of 10.5 m/s?
Answer in units of s.

- How far has the car moved during the
braking period?
Answer in units of m.

Which of the following would not be taken into consideration when describing the quality of a sound

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
