A volleyball starts from rest and accelerates with an acceleration of 0.405 m/s2 while moving down a 8.75 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 15.00 m, it comes to rest.
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?
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.
1. Which of the following kinematic equations would you use to determine the velocity of the car after skidding on the dry pavement for 70 m?
2. Determine the velocity of the car after skidding on the dry pavement for 70 m.
