There is a compressed spring between two laboratory carts of masses m1 and m2. Initially, the carts are held at rest on a horizontal track (Fig. P10.40A). The carts are released, and the cart of mass m1 has velocity
a. What is the net external force on the two-cart spring system?
b. Find an expression for the velocity of cart 2.
c. Sometimes, mistakes are made in a laboratory. For example, what changes in parts (a) and (b) if the track is not level as shown in Figure P10.40C? Explain your answer.

- (a) The springs of a pickup truck act like a single spring with a force constant of 1.30105 N/m . By how much will the truck be depressed by its maximum load of 1000 kg? (b) If the pickup truck has four identical springs, what is the force constant of each?arrow_forwardTable P16.59 gives the position of a block connected to a horizontal spring at several times. Sketch a motion diagram for the block. Table P16.59arrow_forwardA small ball is tied to a string and hung as shown in Figure P8.34. It is released from rest at position 1, and, during the swing, the string meets a fixed peg as shown. Explain why position 2 at which the ball comes momentarily to rest must be at the same height as position 1.arrow_forward
- A block of mass m = 2.00 kg is attached to a spring of force constant k = 500 N/m as shown in Figure P7.15. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. Find the speed the block has as it passes through equilibrium if (a) the horizontal surface is frictionless and (b) the coefficient of friction between block and surface is k = 0.350.

- A 2.50-kg block on a horizontal floor is pushed against a horizontal spring that is initially compressed 0.0300 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is ??=0.30. The block and springare released from rest, and the block slides along the floor. a.What is the speed of the block when it has moved a distance of 0.0200m from its initial position? (At this point the spring is compressed 0.01 m.) b.What distance does the block travel from its initial position to where the block finally stops? (The block leaves the spring when the spring is unstretched or uncompressed).arrow_forwardA block of mass 2.1 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 525 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 12 degrees. a. The block, starting from rest, slides down the ramp a distance 68 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes back to momentary rest? b. After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring? c. What is the change of the gravitational potential eneregy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?arrow_forward
