Explain in detail how to solve: When a car is 100 m from the
entrance of a highway, the driver decides to accelerate at a=3.5m/s
i (for some defined x-axis) for 2.40 s. If the car’s initial
velocity isVo=14.2m/s j,
(a) What is the car’s velocity vector at the end of the 2.40 s
interval?
(b) What is the position of the car – relative to the highway’s
entrance - at t = 2.40 s?
(c) What is the displacement of the car at the end at t = 2.40
s?

When the drivers pass each other, the driver of the red car is
to toss a package of contraband to the other driver. To catch the
toss on video, one of the cameras must be set up near the point
where the toss will be made. When “action” is yelled out on the
set, the initial separation between the drivers will be 200 m, the
red car will accelerate from rest at a constant 6.12

3.6 A car is parked on a cliff overlooking the ocean on an incline that makes an angle 24.0o below the horizontal. The absent-minded driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 4.00 m/s2 for a distance of 50.0 m to the edge of the cliff which is H meters above the ocean. Find the magnitude and direction of the car’s velocity when...
