Express your answer to three significant figures and include the appropriate units. Determine the magnitude of the acceleration of point C. Express your answer to three significant figures and include the appropriate units.arrow_forwardYou will be studying velocity and acceleration of a point undergoing uniform circular motion. This lab is based on the theory presented in Chapter 8 of the Knight (5th edition) textbook. Centripetal acceleration The point P is on a disc rotating counter-clockwise at constant angular speed with period T. Consider the instant when P is at its "right-most” position, and using the coordinate system shown (Fig. 1). C is the centre of the disc. Question 1: In terms of î and ĵ, what is the direction of the velocity of P? Show this direction in Fig 1. Question 2: In terms of î and ĵ, what is the direction of the acceleration of P? Show this direction in Fig 1. Question 3: What is the angular speed (w) of P, in terms of T? Question 4: What is the magnitude of the velocity of P, in terms of (possibly) Rdisc, Rp and w? Question 5: What is the magnitude of the acceleration of P, in terms of (possibly) Rdisc, Rp and w? Question 6: Fill in the theoretical values of the x and y components of velocity…arrow_forward
- B Fig. 2 The 55-kg package at Point A is rolling on a smooth ramp, where the ramp has two circular arcs AB and CD. Section BC is a straight path and the radius of CD is r= 27 m. The heights of the ramp at a and b are given as a = 10 m and b = 35 m. At point A, the package is initially at rest and then rolls freely along the ramp until it reaches point D and lands onto a cart. The air resistance and rolling resistance are ignored. a) Determine the normal component of acceleration at point B. b) Determine the normal force exerted by the ramp on the package at points B and D.arrow_forwardLog Ride (object sliding down a circularly curved slope). In an amusement park ride, a boat moves slowly in a narrow channel of water. It then passes over a slope into a pool below as shown. The water in the channel ensures that there is very little friction. A B (R Ax On this particular ride, the slope (the black arc through points A and B) is a circular curve of radius R, centered on point P. The dotted line shows the boat's trajectory. At some point B along the slope, the boat (and the water falling with it) will separate from the track and fall freely as shown. Note that the pond is level with point P. Considering the boat as a particle, assume it starts from rest at point A and slides down the slope without friction. a) Determine the angle øsen at which the boat will separate from the track. b) Determine the horizontal distance Ax (from point P) at which the boat strikes the pond surface. c) Determine the impact speed vf and impact angle 0.

The radius of the circular loop is r. a) Find a formula for the normal force of the track on the roller coaster, as a function of m, g, v, and r. b) Find a formula for the speed at which the normal force goes to zero. (By the way, at this speed, the roller coaster will start to lift off of the track and the passengers will feel completely weightless.) c) Let's put some numbers in the formula. If the curved track at the top of a crest is 20 m (about 60 ft) in radius, find the speed in m/s and mi/hr at which the car would lift off the track.arrow_forward
