A light spring having a force constant of 105 N/m is used to pull a 6.50 kg sled on a horizontal frictionlessice 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 horizontallyb. 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 valueof the motion they produce. One well-known application shown in is a babybouncer, 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 thebaby to hang in the seat with his or her feet just touching the ground so thatgood push up will get the baby bouncing, providing potentially hours ofentertainment.a. The following chart and accompanying graph shown indepict an experiment to determine the spring constantfor a baby bouncer. What is the spring constant k of thespring being tested for the baby bouncer?b. One of the greatest difficulties with setting up the babybouncer is determining the right height above the floorso that the child can push off and bounce. Knowledge ofphysics can be really helpful here. If the spring constantk = 5.0×10²N/m, the baby has a mass m=11kg, and thebaby's legs reach a distance d=0.15m from the bouncer,what should be the height h of the "empty" bouncerabove the floor?unstenfeExample Data forBaby Bounce Spring9.8HEDhe's awモ=hDXTun0 0.005 0.0I 0.015 0.02Displacement (meters)E lONO-2mSaN%3D

Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.
