As the car drives over the speed bump, the four springs in the suspension compress to absorb energy. The four springs (k = 95,000 N/m) each compress 0.1000m as the car drives over the speed bump. The suspension in a car uses springs to absorb the shock when a car hits a bump in the road or travels over a pothole. Each pair of wheels has two identical springs to absorb the energy of the car. What is the total elastic potential energy from the four springs as the car drives over the speed bump? Show your calculations. A 150-kg car with a velocity of 9 m/s is traveling over a hill of height h. At the bottom of a hill, the car hits a speed bump I without applying the brakes. The velocity of the car at the bottom of the hill before hitting the bump is 13 m/s. The velocity of the car as it goes over the speed bump is 12 m/s. The car then stops at the bottom of the hill.

The string on a bow can be described as a spring. A particular bow’s string has a spring constant of 110 N/m and is pulled back 0.6 m to launch a 0.02 kg arrow. If the bow has a mass of 1 kg, what will be the speed at which the arrow is launched?

2.

(8c7p50) A 0.45 kg mass sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (with k = 725 N/m) whose other end is fixed. The mass has a kinetic energy of 12.0 J as it passes through its equilibrium position (the point at which the spring force is zero). At what rate is the spring doing work on the mass as the mass passes through its equilibrium position? Submit Answer Tries 0/5 At what rate is the spring doing work on the mass when the spring is compressed 0.091 m and the mass is moving away from the equilibrium position?

A child's toy consists of a piece of plastic attached to a spring in the figure below. The spring is compressed against the floor a distance of 2.00 cm, and the toy is released. If the toy has a mass of 115 g and rises to a maximum height of 80.0 cm, estimate the force constant of the spring. N/m

You attach your 4.58 - kg Physics for Engineers book to a horizontal spring (k = 549 N/m). You then pull the book to a distance of 6.7 cm and released it from rest. If the coefficient of kinetic friction between your book and the surface is 0.31, calculate the block's speed as it passes through its original position.

A 1.81-kg box rests atop a massless vertical spring with k = 3820 N/m that has been compressed by 11.4 cm from its equilibrium position. The box is released and leaves the spring when it reaches its equilibrium position. What is the maximum height the box reaches above its original position? In m
