As per guidelines, the first question is answered and the remaining questions to be answered post them separately. 5.3a. (a) Use conservation of energy to find the speed of the box at the bottom of the track. 12mvb2=mghvb=2gh=29.8 m/s23.23 m=7.96 m/s(b) The speed of the box at the given height is given by mgy+12mv2=mgh2gy+v2=2gh v=2gh-y=29.8 m/s23.23 m-1.25 m=6.23 m/s

Current Attempt in Progress A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.39 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A. B
