LONG QUIZ NUMBER 2 FOR PHYSICS l l. A tractor pulls a loaded wagon with a constant force of 440N. If the total mass of the wagon and its contents is 275kg, what is the wagon's acceleration?(ignore any frictional forces). What if the masses of the wagon and the contents had been given separately the rst mass is 75kg and the second mass is 200kg ,the frictional force is 140N, what will be the acceleration of the wagon? If the wagon start from rest, how far it traveled in 4.003? 2. A student weighs 588N. What is her mass? 3. Two blocks with masses, 2.5kg and 3.5kg, rest on a frictionless surface and are connected by a light string. A horizontal force of 12N is applied to the rst mass. (a) what is the magnitude of the acceleration of the masses? (b)What is the magnitude of the force in the string? 4. A block ofmass 0.50kg travels with a speed of 2m/s in the x- direction on a at, frictionless surface. On passing through the origin, it experiences a constant force of 3N at an angle of 60 degrees relative to the X-axis for 1.53. What is the velocity of the block at the end of this time? 5. A car travelling at 72km/h along a straight, level road is brought uniformly to a stop in a distance of 40.0m. If the car weighs 83x10\"? , What is the braking force? 6. The Atwood Machine consists of two masses suspended form a xed pulley. If the rst mass is 0.55kg and 0.8kg, (a) what is the acceleration of the system? (b) What is the magnitude of the tension in the string? (consider the pulley to be frictionless and the masses of the string and the pulley to be negligible.) 7. A force of lSN is applied at an angle of 30 degrees to the horizontal on a 0.750kg block at rest on a frictionless surface. (a) What is the magnitude of the resulting acceleration of the block? (b) what is the magnitude of the normal force? 8. Two masses are connected by a light string running over a light pulley of negligible friction. One mass is the rst mass that is 5kg is on frictionless 20 degrees inclined plane, and the other 1.5kg is freely suspended. What is the acceleration of the masses? 9. A 3kg sign hangs in a hall in the Physics Department . What is the tensile strength necessary for the cord that is used to hang the sign? 10. If the coefcient of static friction between 40kg crate and the oor is 0.65, with What horizontal force must the worker pull to move the crate? If the worker maintains that force once the crate that starts to move and the coefcient of kinetic friction between the surfaces is 0.500, what is the magnitude of the acceleration of the crate
