Question

Problem (4) The motor at C pulls in the cable with
an acceleration ac = 3t² m/s², where t is in seconds.
The motor at D draws in its cable at a = 5 m/s². If
both motors start at the same instant from rest when
d = 3 m, determine:
B
= 0, and
A
-d=3m-
(a) the time needed to get to d
(b) the relative velocity of block A with respect to block B when this occurs.

The known elevations of the ski jumping hill shown below are as follows: hB = 1.2 mhC = 6.4 m If a ski jumper starts from rest at position A, what elevation (in m) is required at position A to ensure that she reaches a minimum launch velocity of 27.1 m/s at position C ?
A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d = 2.67m, and x and y are measured in meters as usual.
