A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 5.30m / (s ^ 2) over a distance of 21.2 cm. It then decelerates at a constant rate of 0.99m / (s ^ 2) (because of friction), until it again comes to rest. Find the total time the block is in motion?
A car is traveling on a straight, level road under wintry conditions. Seeing a patch of ice ahead of her, the driver of the car slams on her brakes and skids on dry pavement for 70 m, decelerating at 6.0 m/s2. Then she hits the icy patch and skids again. The car takes a duration of 85.0 s to come to rest during the second skid. If her initial speed was 50 m/s, what was the magnitude of the deceleration on the ice during the second skid.
A typical sneeze expels material at a maximum speed of 44.9 m/s. Suppose the material begins inside the nose at rest, 2.00 cm from the nostrils. It has a constant acceleration for the first 0.250 cm and then moves at constant velocity for the remainder of the distance.
What is the acceleration as the material moves the first 0.250 cm?
