A cart starts from rest at the top of the tilted track. Assume the track is frictionless. The cart passes photogate A moving at speed3.4cm/s, and passes photogate B moving at speed 8.6cm/s. The distance between point A and point B is 87.3cm.
a) Find the magnitude of the acceleration of the cart.
b) Find the distance from the top of the track to point A.
c) Find the time it took for the cart to move from point A to point B.
A force F = 200i - 400j + FZ k N, is acting through point A(0,0,0) m. If F creates a moment component of -3000 Nm in the direction of a line passing from point B (2,4,5) m to point C(-3,6,8) m
