3. A light spring having a force constant of 105 N/m is used to pull a 6.50 kg sled on a horizontal frictionless
ice rink. The sled has an acceleration of 2.30 m/s?.
a. By how much does the spring stretch if it pulls on the sled horizontally
b. By how much does the spring stretch if it pulls on the sled at 37.0 °above the horizontal?
4. Toy makers have always been interested in springs for the entertainment value
of the motion they produce. One well-known application shown in is a baby
bouncer, which consists of a harness seat for a toddler, attached to a spring.
The entire contraption hooks onto the top of a doorway. The idea is for the
baby to hang in the seat with his or her feet just touching the ground so that
good push up will get the baby bouncing, providing potentially hours of
entertainment.
a. The following chart and accompanying graph shown in
depict an experiment to determine the spring constant
for a baby bouncer. What is the spring constant k of the
spring being tested for the baby bouncer?
b. One of the greatest difficulties with setting up the baby
bouncer is determining the right height above the floor
so that the child can push off and bounce. Knowledge of
physics can be really helpful here. If the spring constant
k = 5.0×10²N/m, the baby has a mass m=11kg, and the
baby's legs reach a distance d=0.15m from the bouncer,
what should be the height h of the "empty" bouncer
above the floor?

Back when I was a kid, I loved to play with my Hot Wheels. Hot Wheels are miniature metal cars that race down lengths of flexible track. The track comes in segments that can be connected together. One thing you can do is make the cars Loop the Loop, as shown in the figure above. Starting at a height, h, the cars race down the track, traverse a circular loop of radius, R, without falling down at the top of the loop, and then continue racing along a section of level track. If the loop is 9 inches in diameter, what is the minimum height, h, from which the cars can start and still loop the loop without falling down at the top? Neglect friction and air resistance.
Two dogs pull horizontally on ropes attached to a post; the angle between the ropes is 67.0 degrees. Dog A exerts a force of 282 N, and dog B exerts a force of 348 N. 1st) Find the magnitude of the resultant force. 2nd) Find the angle the resultant force makes with the rope of dog A.
Multiple Choice: Which of the following is true. A. The magnitude of a force is positive only if it is pointing up. B. The magnitude of a force means the same thing as the numerical value of the strength of that force. C. The magnitude of a force is negative if the force points down. D. All of the above are correct.
