A student is asked to measure the acceleration of a glider on a frictionless, inclined plane, using an air track, a stopwatch, and a meterstick. The top of the track is measured to be 1.774 cm higher than the bottom of the track, and the length of the track is d = 127.1 cm. The cart is released from rest at the top of the incline, taken as x = 0, and its position x along the incline is measured as a function of time. For x values of 10.0 cm, 20.0 cm, 35.0 cm, 50.0 cm, 75.0 cm, and 100 cm, the measured times at which these positions are reached (averaged over five runs) are 1.02 s, 1.53 s, 2.01 s, 2.64 s, 3.30 s, and 3.75 s, respectively. (a) Construct a graph of x versus t2, with a best-fit straight line to describe the data. (b) Determine the acceleration of the cart from the slope of this graph. (c) Explain how your answer to part (b) compares with the theoretical value you calculate using a = g sin as derived in Example 4.3.
Why is the following situation impossible? In a new casino, a supersized pinball machine is introduced. Casino advertising boasts that a professional basketball player can lie on top of the machine and his head and feet will not hang off the edge! The hall launcher in the machine sends metal halls up one side of the machine and then into play. The spring in the launcher (Fig. P7.44) has a force constant of 1.20 N/cm. The surface on which the ball moves is inclined = 10.0 with respect to the horizontal. The spring is initially compressed its maximum distance d = 5.00 cm. A ball of mass 100 g is projected into play by releasing the plunger. Casino visitors find the play of the giant machine quite exciting. Figure P7.44
An ornament of mass 46.5 g is attached to a vertical ideal spring with a force constant of 22.4 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch? Give answer in cm
A 3 kg object attached to an ideal massless spring is compressed 1.2 m. If the spring constant is 45 N/m, find the magnitude of the spring force.
A block with mass m1 = 8.7 kg is on an incline with an angle θ = 37° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: μk = 0.36 and μs = 0.396. To keep the mass from accelerating, a spring is attached. What is the minimum spring constant of the spring to keep the block from sliding if it extends x = 0.17 m from its unstretched length?

The cable of a 1800 kg elevator snaps when the elevator is at rest on the first floor. The elevator cab is d = 3.7 m above a spring of spring constant 0.15 MN/m (M = 106). A safety device clamps the cab against guide rails so that a constant frictional force of 4.4 kN (k = 1,000) opposes the cab's motion. Determine the maximum distance the spring is compressed (the friction force still acts during this compression). Use g = 9.8 N/kg.
A light spring obeys Hooke's law. The spring's unstretched length is 32.0 cm. One end of the spring is attached to the top of a doorframe and a weight with mass 8.25 kg is hung from the other end. The final length of the spring is 44.5 cm. Find its spring constant (in N/m). If the weight and the spring are taken down and two people pull in opposite directions on the ends of the spring, each with a force of 150 N. Find the length (in m) of the spring in this situation. From the answer in b), what would be the length (in m) of the spring if it was now attached to the vertical portion of the doorframe and stretched horizontally by a single person exerting a force of 150 N?
