subway car leaves station A; it gains speed at the rate of 4ft /s2 for 6 s and then at the rate of 6ft /s2 until it has reached the speed of 48 ft/s. The car maintains the same speed until it approaches station B; brakes are then applied, giving the car a constant deceleration and bringing it to a stop in 6 s. The total running time from A to B is 40s. Determine the distance between stations A and B.

2. A speed skater increases his speed from 10 m/s to 12.5 m/s over a period of 3 seconds while coming out of a curve of 20 m radius. What are the magnitudes of his tangential, centripetal, and resultant accelerations as he leaves the curve?
A disk rotating with constant acceleration of 0.005 revolutions / s2 And the movement starts from rest. What is the angle velocity after one minute? How many turns makes the same disc in point number one after one minute. If an external force does not affect the body, what does that mean? And if the body is in free fall, is its speed constant or variable, what is its acceleration equal, and how can the friction be reduced between the contact surfaces

BOX THE FINAL ANSWER.USE 9.81m/s2 or 32.2 ft/s2 for accelaration if necessary.) Determine the time and displacement of the ball at the same height from the ground.
When a volleyball coach releases a volleyball from a height of 2 m above the gym floor, it falls to the floor and bounces back to two-thirds the same height. When it is in contact with the floor, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is 1 cm. (Assume the positive direction is upward.)1. Determine the acceleration of the ball (in m/s2) while it is in contact with the floor and compressing. (Indicate the direction with the sign of your answer.) 2. Determine the velocity of the ball (in m/s) as it leaves the floor on the rebound. (Indicate the direction with the sign of your answer.) 3. What If? If instead of dropping the ball, the coach throws it down (from some unknown height) with such a speed that it bounces back up to a height three times its original height, determine the new acceleration of the ball (in m/s2) while in contact with the floor and expanding. (Indicate the direction with the sign of your answer.)
The engine in an imaginary sports car can provide constant power to the wheels over a range of speeds from 0 to 70 miles per hour (mph). At full power, the car can accelerate from zero to 29.0 mph in time 1.00 s . You do not have to show your work. A At full power, how long would it take for the car to accelerate from 0 to 58.0 mph ? Neglect friction and air resistance. Express your answer in seconds. B A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a constant force (in contrast to the constant power in Part A). If such a sports car went from zero to 29.0mph in time 1.00s , how long would it take to go from zero to 58.0mph ?

A car moves along a straight line whose equation of motion is given by V =4t2-2t+2 where (V) is in meter per second and (t) is in seconds. After 3 seconds from the start the linear displacement was 35m. When t = 6 seconds, determine the linear displacement, linear velocity and linear acceleration of the car.
Q1. A driver enters a curved car at 72 km/h, slows down, causing the speed to drop at a steady rate of 4.5 km/h every second. If the radius of curvature is 16.7 m. Find the acceleration of the car after 4 seconds from the driver starting to slow down.

Modern roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. Part (a) What is the speed of the roller coaster, in meters per second, at the top of the loop if the radius of curvature there is 15 m and the downward acceleration of the car is 1.3g? Note that g here is the acceleration due to gravity. Part (b) The beginning of this roller coaster is at the top of a high hill. If it started from rest at the top of this hill, how high, in meters, above the top of the loop is this initial starting point? You may assume there is no friction anywhere on the track. Part (c) If it actually starts 3.5 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose…
