An air-track glider of mass 0.100 kg is attached to the end of a horizontal air track by a spring with force constant 20.0 N/m. Initially the spring is unstreched and the glider is moving at 1.50 m/s to the right. With the air track turned off, the coefficient of kinetic friction is μk=0.47. It can be shown that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously. If the coefficient of static friction...

Question 2 (6 marks) A vane with an angle of 30° is attached to a cart (Figure 2). The cart and vane (mass of 75 kg) move on a level track with a constant speed of 10 m/s. The vane receives a jet of water (p = 1000 kg/m) that leaves a stationary nozzle with speed of 35 m/s. The nozzle exit area is 0.003 m². Assume that this cross-sectional area of the water stream does not change as it...

An air-track glider of mass 0.109 kg is attached to the end of a horizontal air track by a spring with force constant 24.5 N/m (a) With the air track turned off, the glider travels 8.0 cm before it stops instantaneously. How large would the coefficient of static friction μs have to be to keep the glider from springing back to the left? (b) If the coefficient of static friction between the glider and the track is μs= 0.65, what...

TCTIOUN Fan Block A student in a physics lab has a block with a fan attached to it, as shown in the figure above. The fan has a pivot so that the angle e it makes with the horizontal can be adjusted between 0° and 90°. When the fan is pointed horizontally so that 0 0°, the block accelerates from rest along a track, even though there is friction between the block and the track. For the following questions, assume...

A cart of mass 260 g is placed on a frictionless horizontal air track. A spring having a spring constant of 8.0 N/m is attached between the cart and the left end of the track. The cart is displaced 3.5 cm from its equilibrium position. (a) Find the period at which it oscillates. s (b) Find its maximum speed. m/s (c) Find its speed when it is located 2.0 cm from its equilibrium position. m/s

Question 22 of 22 > Track ... Rope . A cart for hauling ore out of a gold mine has a mass of 445 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.55° incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 444 N force for a distance of 201 m by means...

O/6 points The figure below shows an arrangement with an air track, in which a cart is connected by a cord to a hanging block. The cart has mass m10.680 kg and its center is initially at xy coordinates (-0.500 m, 0 m). The block has mass m20.260 kg and its center is initially at xy coordinates (O, -0.100 m). The mass of the cord and pulley are negligible. The cart is released from rest, and both cart and block...

Problem two: Cari won.no Track A frictionless cart of mass M is attached to a spring with spring constant k. When the cart is displaced 6 centimeters from its rest Rest position position and released, il oscillates with a period of 2 seconds. Four students are discussing what would happen to the period of oscillation if the original cart with mass M was displaced 12 cm o O from its rest position instead of 6 cm and again released: Ava:...

1a- A 140-gram glider on a horizontal, frictionless air track is attached to a fixed ideal spring with force constant 173 N/m. At the instant you make measurements on the glider, it is moving at 88.7 cm/s and is 3.79 cm from its equilibrium point. Use energy conservation to find: (iii) - what is the angular frequency of the oscillations, in rad/s? 1b- A 1.9-kg monkey wrench is pivoted 0.31 m from its center of mass and allowed to swing...
