Two masses,m1 and m2, are connected to each other as shown. Mass m1
slides without friction on the table surface. Both masses have an
acceleration of magnitude as shown. How does the tension in the string
compare to the weight, m2g.
m1
m2
The tension is larger than m2g
The tension is equal to m2g
The tension is smaller than m2g
It depends on m1 being smaller than m2
O It depends on m1 being larger than m2
A 7 kg mass is placed on a table with Ms= 0.18 and Mk= 0.15. How much mass must be suspended on m in order to start the 5 kg moving? What is the resulting acceleration? This is basically the situation we set up in Lab several times…... a pulley system is placed such that the weight of mass 2 will pull horizontally to the table the 7 kg is placed upon.
You throw a baseball straight upward with speed v0. When the ball returns to the point from where you threw it, how does its speed compare to v0 (a) in the absence of air resistance and (b) in the presence of air resistance? Explain.
