Forces and Newton's LAWS WU PHYS 1107 - General Physics I ) An 9.0 kg mass (M) is placed on a horizontal surface. A massless rope runs over a frictionless massless pulley which connects the mass M to a 6.5 kg mass (m) that hangs vertically. a) What is the acceleration of the vertical mass if the horizontal surface is frictionless? b) What is the tension in the rope if the horizontal surface is frictionless? Now assume that the horizontal...
Physics: Work and Energy/Momentum
A 6.00 Kg mass initially at rest slides down a ramp which makes
an angle of with horizontal at a
height of 5.0 m above the bottom of the slide and hits a 10.00 Kg
mass which is at rest, after collision, the 6.00 Kg mass bounces
back with a velocity of 0.60 m/s and 10.0 kg mass slides forward on
level. If the coefficient of kinetic friction for the incline is
0.30 and level is...
Interactive Exercises 5.14: Applying Newton's Laws (The Double Incline) In a project for a mechanical engineering class, some students make a double incline, in which the angle of the two inclined, smooth surfaces can be separately adjusted by means of a hinge at the top-see Fig. 5.14.1. The angle of the incline on the left side is denoted by the angle φ shown in the figure. The angle of the right incline is denoted by the angle θ. Two blocks,...

Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
