Two blocks, A and B (with mass 50.0 kg and 1.00 102 kg, respectively), are connected by a string, as shown in Figure P5.86. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is k = 0.250. Determine the change in the kinetic energy of block A as it moves from to , a distance of 20.0 m up the incline (and block B drops downward a distance of 20.0 m) if the system starts from rest. Figure P5.86
In a common physics demonstration, a bowling ball is suspended from the ceiling by a rope. The professor pulls the ball away from its equilibrium position and holds it adjacent to his nose, as shown below. He releases the ball so that it swings directly away from him. Does he get struck by the ball on its return swing? What is he trying to show in this demonstration?
Check Your Understanding (a) A car and a truck each moving with the same kinetic energy. Assume that the truck has more mass than the car. Which has the greater speed? (b) A car truck are each moving with same speed. Which has the greater kinetic energy?
How much energy is lost to a dissipative drag force if a 60-kg person falls at a constant speed for 15 meters?
a mother and her child are skiing together, and the mother is holding the end of a rope tied to the child's waist. They are moving at a speed of 7.2 kph on a gently sloping portion of the ski slope when the morher observes that they are approaching a steep descrnt. She pulls on the rope with an average force of 15 N. Knowing the coefficient of frivtion between the mother and the ground is 0.2, the mass of the mother is 62 kg and the angle of the rope does not change, determine the acceleration of the mother, the time reuired dor the mother's speed to be cut in half, and the distance traveled.
Junry pulls his wife, who’s mass is 50 kg and who is sitting on a swing with rope of length 5 m, backward until the rope make an angle of 50° with respect to the vertical. He then releases his wife from rest. Determine the speed of his wife when the rope makes an angle of 20° with respect to the vertical? a. 5.30 m/s c. 5.60 m/s b. 5.50 m/s d. 5.40 m/s
A projectile of mass m is fired horizontally with an initialspeed of v0 from a height of h above a flat, desert surface.Neglecting air friction, at the instant before the projectile hitsthe ground, find the following in terms of m, v0, h, and g : (a) thework done by the force of gravity on the projectile, (b) thechange in kinetic energy of the projectile since it was fired,and (c) the final kinetic energy of the projectile. (d) Are anyof the answers changed if the initial angle is changed?
When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation: v2x =(2P/m)*twhere P=3.6×104 W is the car's power output, m = 1200kg is its mass, and vx is in m/s. That is, the square of the car's velocity increases linearly with time Find a symbolic expression, in terms of P, m, and t, for the car's acceleration at time t.
A stationary but movable 400 kg cannon is fired, and the 10 kg cannonball moves off to the right with a velocity of 20.0 m/s . What is the cannon's speed in m/s (neglecting friction or any restraints )?
Two blocks are connected by a light string that passesover a frictionless pulley as in Figure P5.38. The system is released from rest while m 2 is on thefloor and m1 is a distance h above thefloor. (a) Assuming m 1 >m 2, find anexpression for the speed of m1 justas it reaches the floor. (b) Takingm 1 = 6.5 kg, m 2 = 4.2 kg, andh = 3.2 m, evaluate your answer topart (a), and (c) find the speed ofeach block when m 1 has fallen a distanceof 1.6 m.

Gayle runs at a speed of 4.00 m/s and dives on a sled, initiallyat rest on the top of a frictionless, snow- covered hill. After shehas descended a vertical distance of 5.00 m, her brother, whois initially at rest, hops on her back, and they continue downthe hill together. What is their speed at the bottom of the hillif the total vertical drop is 15.0 m? Gayle’s mass is 50.0 kg,the sled has a mass of 5.00 kg, and her brother has a mass of30.0 kg.
