I need help with part b of the question please.
Transcribed Image Text:1. The system shown below consists of two connected blocks resting on a cart that is held at rest
and then released. The surfaces of the blocks and cart are frictionless, but the cart's wheels are
exerting a kinetic friction force with the ground of coefficient µ
and has negligible mass, the pulley has negligible mass and friction. The cart has mass M =
the top block has mass m
the hanging block has mass m2 = 95.0 kg.
The cart cannot tip.
= 0.0514. The string is inelastic
110 kg,
45.0 kg, and
m,
(a) What is the direction and magnitude
of the acceleration of the cart?
m2
(b) As the hanging block, m2,
decreases in
mass the cart accelerates less. At what
smaller value of m2does the cart stop
accelerating entirely?
