Afriend asks you how much pressure is in your car tires. you know that the tire manufacturer recommends 30 psi, but it's been a while since you've checked. you can't find a tire gauge in the car, but you do find the owner's manual and a ruler. fortunately, you've just finished taking physics, so you tell your friend, "i don't know, but i can figure it out." from the owner's manual you find that the car's mass is 1000 kg . it seems reasonable to assume that each tire supports one-fourth of the weight. with the ruler you find that the tires are 13 cm wide and the flattened segment of the tire in contact with the road is 13 cm long.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
