A roller-coaster car has a mass of 510 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and-down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points O and ® are parts of vertical circles of radius r, = 10.0 m and r, = 15.0 m, respectively. (a) If the vehicle has a speed of 19.8 m/s at point O, what is the force exerted by the track on the car at this point? N (b) What is the maximum speed the vehicle can have at ® and still remain on the track? m/s

A skier is on a 25 degree slope and his mass is 80kg. If his constant velocity and the coefficient of kinetic friction between the ski and the snow is 9 m/s and 0.80, respectively, compute his velocity when he has skid 20m from his initial position and a drag force experienced by the skier equivalent to a magnitude of 0.6V^2.
Assume that the box and disk each have mass m, the top of the incline is at height h, and the angle between the incline and the ground is θ (i.e., the incline is at an angle θ above the horizontal). Also, let the radius of the disk be R.

A projectile of mass [m] is launched with initial velocity [v0] at angle [theta] from the +x direction. From the origin, the projectile is connected toa massless spring with force constant k, as shown. From the equations of motion, one can show that the horizontal and vertical positions of the mass as functions of time can be written asx(t) = A cos wt + B sin wty(t) = C cos wt + D sin wt + Eprovided that the coefficients satisfy the conditions that initially, x(0) = y(0) = 0,vx (t = 0) = v0 cos [theta], and vy (t = 0) = v0 sin [theta]. Determine the coefficients A,B,C,D, and E in termsof the given variables.

A crate of mass m is initially at rest at the highest point of an inclined plane which has a height of 5.28 m and makes an angle of A = 17.2° with respect to the horizontal. After it has been released, it is found to be traveling at v = 0.29 m/s a distance dafter the end of the inclined plane, as shown.
