rough surfice Smooth Swace feed 2.50m he 3.00m E; Ei + WNc m A 34.2 kg block slides with a velocity of 10.22 m/s to the right on a frictionless surface (as shown in the figure above). The block slides up a slope to a height of 3.00 m and then slides across a 2.50 m long rough surface with a coefficient of kinetic friction equal to 0.325. The block continues to travel to the right and bumps into a massless spring with a spring constant (k) equal to 2320 N/m. a) How much does the spring get compressed by the block with respect to its equilibrium length?

Figure P7.44 45. Review. Two constant forces act on an object of mass m = QIC 5.00 kg moving in the xy plane as shown in Figure P7.45. Force F, is 25.0 N at 35.0°, and force F, is 42.0 N at 150°. At time t = 0, the object is at the origin and has velocity (4.00î + 2.50j) m/s. (a) Express the two forces in unit-vector notation. Use unit-vector notation for your other answers. (b) Find the total force exerted on the object. (c) Find the object's acceleration. Now, considering the instant t = 3.00 s, find (d) velocity, (e) its position, its kinetic energy the object's (f) from mv, and (g) its F2 F kinetic from 150° energy mu + EF · A.

A 980-kgkg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. 1.What was the speed sports car at impact? Express your answer to two significant figures and include the appropriate units. V=??
The 1-kg ball is thrown at the suspended 10-kg block with a velocity of 4 m/s. If the coefficient of restitution between the ball and the block is e=0.8, determine the maximum height h to which the block will swing before it momentarily stops. 4 m/s В h A
33. Two blocks are free to slide along the frictionless, AMT Wooden track shown in Figure P9.33. The block of W mass m, = 5.00 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnct, which repels the north pole of an iden- tical magnet embedded in the back end of the block of mass l, 10.0 kg, initially at rest. The two blocks %3D never touch. Calculate the maximum height to which m, rises after the elastic collision. Figure P9.33

9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.
A Box of mass 1.2 kg is dropped from a window. the box starts from rest (inital speed 0). Immediately before hitting the ground the box has a speed of 34.34 m/s. It takes the boxs 0.017s for the box to come to rest after hitting the ground. What is the average net force on the box while it comes to rest. Round to the nearest whole number.
A 325-g model boat facing east floats on a pond. The wind in its sail provides a force of 1.45 N that points 25 north of cast. The force on its keel is 0.613 N pointing south. The drag force of the water on the boat is 0.750 N toward the west. If the boat starts from rest and heads east, what is its final speed by after it travels for a distance of 4.15 m? Uy = -14.4 m/s
