Packages enter the 10.3-ft chute at A with a speed of 2.9 ft/sec and have a 0.29g acceleration from A to B. If the packages come to rest at C, calculate the constant acceleration a (positive if it speeds up, negative if it slows down) of the packages from B to C. Also find the time required for the packages to go from A to C. 10.3' Answers: From B to C, a = From A to C, t= i i 12.4' ft/sec² sec

Derive an expression for the position min x of the block when it is closest to the motion sensor. Express your answer in terms of m, D, 0v , q , and physical constants, as appropriate. On the axes provided below, sketch graphs of position x, velocity v, and acceleration a as functions of time t for the motion of the block while it goes up and back down the ramp. Explicitly label any in Suppose the ramp now has friction. The same block is projected up with the same initial speed 0v and comes back down the ramp. On the axes provided below, sketch a graph of the velocity v as a function of time t for the motion of the block while it goes up and back down the ramp, arriving at the bottom of the ramp at time f t . Explicitly label any intercepts, asymptotes, maxima, or minima with numerical values or algebraic expressions, as appropriate.

Problem-2 A train starts from rest at station A and accelerates at 0.5m/s? for 60 s. Afterwards it travels with a constant velocity for 15 min. It then decelerates at 1m/s? until it is brought to rest at station B. Determine the distance between the stations.

10 mins left. pls help me. I'll give thumbs up
