The 900-lb roller coaster car starts from rest on the track having the shape of a cylindrical helix as shown in figure. The normal force of the tracks on the car has a transverse component of N(theta)=68 lb. A). Determine the transverse component of its velocity in t=4s. Neglect the size of the car. B). What is the car's velocity when it descends 8 ft? Neglect size of the car. I need handwritten only or else skip I'll dislike only handwritten or dislike

The roller coaster and its passenger have a total mass m. Determine the smallest velocity it must have when it enters the loop at A so that it can complete the loop and not leave the track. Also, determine the normal force the tracks exert on the car when it comes around to the bottom at C. The radius of curvature of the tracks at B is p3 , and at C it is Pc. Neglect the size of the car. Points A and C are at the same elevation. B PB

The 4,450kg truck is traveling at 30.50m/s when the brakes on all its wheels are applied, causing it to skid for a distance of 22m before coming to rest. Calculate the constant horizontal force developed in the coupling C, as well as the frictional force developed between the tires of the truck and the road during this time. The combined mass of the boat and trailer is 2,250kg

If the motor draws in the cable with an acceleration of 3 m/s^2, determine the reactions at the supports A and B. The beam has a uniform mass of 30 kg/m, and the crate has a mass of 200 kg. Neglect the mass of the motor and pulleys.

The 188-lb car of an amusement park ride is connected to a rotating telescopic boom. When r= 15 ft, the car is moving on a horizontal circular path with a speed of 25 ft/s. If the boom is shortened at a rate of 5 ft/s, determine the speed of the car whenr= 7 ft. Neglect the size of the car and the mass of the boom.

The small cylinder C has a mass of 10 kg and is attached to the end of a rod whose mass may be neglected. The frame is subjected to a couple of moment M = 26Nm, and the cylinder is subjected to a force of F = (5t² + 6) N, where t is in seconds, which is always directed in the same direction as the cylinder's velocity as shown. The cylinder has a speed vo= 2 m/s when t = 0. (Figure 1) Figure 0.75 m M 1 of 1 Part A Determine the speed of the cylinder when t = 3 s.

The spring is not stretched or compressed when “s=0.8m" and the 11 kg block which is subjected to a force of 105 N has a speed of 5.5 m/s down the smooth plane. Using "THE PRINCIPLE OF WORK AND ENERGY", find the distance "s" when the block STOPS. k = 200 N/m 5 m/s F = 100 N 30°

The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, 0 = 26°, Ò = 50 deg/s, and Ö – 14 deg/s². Determine the magnited of the force Fapplied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.3-kg slider B. Neglect all friction, and let L = 0.74 m. The motion occurs in a vertical plane. B т -L
