... A 45.7 kg circus acrobat drops from a
height of 1.79 meters straight down onto a springboard with a force constant of 5.87 x 103 N/m, as
shown in the figure. By what maximum distance does she compress the spring?
A7. Consider a spring-mass system as shown in the diagram, which consists of 1.0 kg block
held by three identical springs with force constant k = 100 Nm', as shown in Fig. A7.
Fig. A7
(a) Consider the block being displaced by a distance x m to the left. Determine the net
force (both magnitude and direction) acting on the block by the springs.
(b) The block is then released from rest. Show that the block performs simple harmonic
motion, and determine the frequency of oscillation.
The ball launcher in a pinball machine has a spring that has a force constant of 50.0 N/m. The surface on which the ball moves is inclined 10.0° with respect to the horizontal. The spring is initially compressed 5.00 cm. Find the distance along the incline that the ball will go to (from the mean position of the spring), if the friction force = 0.1N. Mass of the ball = 20 gram.
