In a recent test of its braking system, a Volkswagen Passat traveling at 31.2 m/s came to a full stop after an average negative acceleration of magnitude 2.10 m/s2.
(a) How many revolutions did each tire make before the car comes to a stop, assuming the car did not skid and the tires had radii of 0.350 m?
(b) What was the angular speed of the wheels (in rad/s) when the car had traveled half the total stopping distance?
A boat moves with a constant velocity of 6m.s, starting from the position
shown. Find (a) the angle in order for the projectile to hit the boat 5sec
after starting under the condition given,(b) How high is the ill above the
water?

Garen observed his athletic friends, Aya and Marisa, run. The two girls ran in a 1.5-km straight dirt road. Marisa was a given a ten-second head-start. When Aya ran, she caught up with Marisa, who ran at 3.75 m/s. Both of them finished the 1000 m run, with Aya measured to finish the track at 375 seconds. How fast was Aya?
The position of a particle moving along the x axis is given by , where x is in meters and t in seconds. What is the position of the particle when it achieves its maximum speed in the positive x direction?

Calculate the force of gravitational attraction between the earth (m = 5.98 x 1024 kg) and a 75-kg
physics student if the student is standing at sea level, a distance of 6.38 x 106 m from earth's center.
A train starts from rest at a station and accelerate at a rate of 2 m/s2for 10 s. It then runs at constant speed for 30 s, and slows down at -4 m/s2 until it stops at the next station. Find the total distance covered
10 m/s.
