5. In the Atwood machine, shown on the diagram, Show all the steps for the following questions: a) an equation for the magnitude of the acceleration of the two blocks (Use the following as necessary: m1, m2, and g for the magnitude of the acceleration due to gravity. Assume m2 > m1.) m1 es over b) an equation for the tension in the string (Use the following as necessary: m1, m2, and g.) cord m2 c) both the magnitude of the acceleration (in m/s2) and tension (in N) when block 1 has mass 4.00 kg and block 2 has mass 7.00 kg.

Cam Newton of the Carolina Panthers throws a perfect football spiral at 8.0 rev/s. The radius of a pro football is 8.5 cm at the middle of the short side. What is the centripetal acceleration of the laces on the football?

A telephone pole has three cables pulling as shown from above, with and (a) Find the net force on the telephone pole in component form. (b) Find the magnitude and direction of this net force.

Speed is a(n) ___ quantity. (2.2)

A 15-kg sled is pulled across a horizontal, snow-covered surface by a force appiled to a rope at 30 degrees with the horizontal. The coefficient of kinetic friction between the sled and the snow is 0.20. (a) If the force Is 33 N, what is the horizontal acceleration of the sled? (b) What must the force be in order to pull the sled at constant velocity?

While sliding a couch across a floor, Andrea and Jennifer exert forces FA and FJ on the couch. Andrea’s force is due north with a magnitude of 130.0 N and Jennifer’s force is 32 east of north with a magnitude of 180.0 N. (a) Find the net force in component form. (b) Find the magnitude and direction of the net force. (c) If Andrea and Jennifer’s housemates, David and Stephanie, disagree with the move and want to prevent its relocation, with what combined forceFDS should they push so that the couch does not move?

Try the following experiment away from traffic: where you can do it Safely. With the car VOU are driving moving slowly on a Straight, level road, shift the transmission into neutral and let the car coast. At the moment the car comes to a complete slop, step hard on the ln.ike and notice what you feel. Now repeal I he same experiment on a fairly gentle, uphill slope. Explain the difference in what a pet son tiding in the car feels in the two cases. (Brian Popp suggested the idea for this question.)

Dimensions What frame or frames of reference do you use instinctively when driving a car? When flying in a commercial jet?

A sledge is being pulled by two horses on a flat terrain. The net force on the sledge can be expressed in the Cartesian coordinate system as vector , where and denote directions to the east and north, respectively. Find the magnitude and direction of the pull.

Why does banking a curve on a highway allow a vehicle to successfully negotiate the turn at a higher speed?
