3*) It is common to see birds of prey rising upwards on thermals. The paths they take may be spiral- like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume a bird completes a circle of radius 8.00 m ever 5.00 s and rises vertically at a rate of 3.00 m/s. Determine a) the speed of the bird relative to the ground, b) the bird's acceleration (magnitude and direction) and c) the angle between the bird's velocity vector and the horizontal. (a: 10.5 m/s, b: 12.6 m/s² toward center of spiral, c: 0.29 rad)

Problem In a relief operation mission involving a helicopter h distance above the ground traveling with a horizontal velocity vx. What should be the expression for the horizontal distance dx at which you release the relief package so that it will arrive to the survivors at the right place? (Neglect the effect of air resistance) Solution To determine this, we must first derive the time it takes for the relief package to reach the survivors. We use this equation -h = vinitial-yt + (1/2)ay________________ If we just drop the package from the helicopter, the equation above becomes ________________=________________ + (1/2)ay_____________________ Substituting ay = -g then simplifying results to t = sqrt( _____________/______________ ) which is the time it takes for the object to reach the ground. Since the package will just travel at a constant velocity in the x-axis, thus dx = vxt Substituting the time taken by the package to reach to ground results to: dx = ( _________ )( sqrt…

VCM-2 As Khanh is driving her car along a straight road with a constant speed, she passes over a series of hills and dips. Each dip and hill has a radius of curvature of 250m She has a 5.00kg package sitting on a scale on the seat beside her. On one stretch of the road she passes thru a dip and then over a hill as shown below. a) Use the velocity vectors shown for V1 and V2, the velocities just before and just after the bottom of the dip, to show the direction of AV, the change in velocity in going thru the bottom of the dip. R=250m Car at the top of the hill. Car at the bottom of the dip. V2 b) Apply Fnet-ma to write symbolic equations for the package when it is in the car at the bottom of the dip. Include all forces on the package. If something equals zero, show it here, otherwise use no numbers in this step. R=250m
