If you increase the 'k' value of the spring, the more difficult you are making it to compress or stretch it. True or False

(a) The springs of a pickup truck act like a single spring with a force constant of 1.13 x 105 N/m. By how much will the truck be depressed (in cm) by its maximum load of 1473 kg? cm (b) If the pickup truck has four identical springs, what is the force constant of each? (Enter your answer in N/m.)

1. A heavy crate (m = 23 kg) is resting on a frictionless inclined plane while suspended from a wall by a spring. The plane is inclined at an angle of 30° from the horizontal, and the spring is stretched from its equilibrium position by 25 cm. What is the spring constant of the spring? If the frictionless inclined plane is now replaced with an otherwise identical plane except with a rough surface, the crate now stretches the spring by 12 cm from its equilibrium position. What is the coefficient of static friction? You can assume that the static friction is at its maximum value. 30°
