An inventive child wants to pick up an apple in a tree without climbing the tree. He sits on a chair connected to the rope and pulley without friction. The child pulls the end of the rope with such a force that the scale of the spring is 250 N. The weight of the child is 320 N, and the weight of the chair is 160 N. (a) Draw a free-body diagram for the child and the chair as a separate system, and another diagram for the child and the chair as one system! (b) Calculate the acceleration of the system! (c) Also count the force the child exerts on the chair!

Two blocks are connected by a light string that passes over two frictionless pulleys as in Figure P5.24. The block of mass m2 is attached to a spring of force constant k and m1 m2. If the system is released from rest, and the spring is initially not stretched or compressed, find an expression for the maximum displacement d of m2. Figure P5.24
The systems shown in Figure P4.58 are in equilibrium. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline in Figure P4.58d are frictionless. Figure P4.58
Air track: two objects tied together by a string. The figure shows a glider with mass my that moves on a level, frictionless air track in a physics lab. It is connected by a string passing over a small frictionless pulley to a hanging weight with total mass m₂. The string is light and flexible, and it doesn't stretch. (a) Find the acceleration of each object and the tension in the string. (b) What happens to the acceleration when m, is two times heavier than that of m₂? (c) Now my is four times heavier than that of m₂. Calculate the distance between it traveled during the initial period of two (2) seconds after the glider started moving. The tract is long enough for the travel. Show your work that leads to your answer. Explain each step in your work to explanation -quation WILIT T
You have a new internship, where you are helping to design a new freight yard for the train station in your city. There will be a number of dead-end sidings where single cars can be stored until they are needed. To keep the cars from running off the tracks at the end of the siding, you have designed a combination of two coiled springs as illustrated shown. When a car moves to the right in the figure and strikes the springs, they exert a force to the left on the car to slow it down. Both springs are described by Hooke’s law and have spring constants k1 = 1 600 N/m and k2 = 3 400 N/m. After the first spring compresses by a distance of d = 30.0 cm, the second spring acts with the first to increase the force to the left on the car as shown. When the spring with spring constant k2 compresses by 50.0 cm, the coils of both springs are pressed together, so that the springs can no longer compress. A typical car on the siding has a mass of 6 000 kg.…
A 0.75-kg cart is pulled along a horizontal track by a rope. The rope makes an angle of 30 degrees to the horizontal. Your friend says that the normal component of the force the track exerts on the cart is 7.5 N because mg = (0.75kg) (¹0N) = 7.5N. Do you agree with your friend? Use a force diagram and Newton's 2nd Law to explain why.

The figure shows a system in equilibrium, composed of three bodies connected through an ideal rope that passes through a pair of pulleys, also ideal. Consider that there is no friction in the entire system. Draw the Free Body Diagram (FBD) of each body and write the system of equations that describe the system. Joog
To raise money for a university scholorship fund, the new IT dean has volunteered to bungee jump from a crane if contributions can be found for 10 scholarshipis. To add some interest, the jump will be made from 42 m above a pool of water. A 30 m bungee cord would be attached to the dean. First you must convince the dean that your plan is safe for a person of his mass, 70 kg. The dean knows that as the bungee cord begins to stretch, it will exert a force which has the same properties a the force exerted by a spring. Your plan has the dean stepping off a platform and being in free fall for 30 m before the cord begins to stretch. a) Determine the spring constant of the bungee cord so that it stretches only 12 m, which will just keep the dean out of the water. (Assume that the dean is a point like object). b) Using the result of a), find the dean's speed 7 m above the water.
10 of 31 Listen Study the scenario. A car is moving along a frictionless surface with a speed of 2 m/s to the left. You and your friend each come over and push the car at the same time. You exert a force of 6 N to the left, while your friend exerts a force of 6 N to the right. According to Newton's first law, how will this action affect the car's motion? The car will speed up because your force is in the same direction of the car's motion, making it speed up. The car will stop immediately because two balanced forces will cause an object to stop moving. The car will continue moving to the left but at a slower speed because your friend's force is going to make the car slow down. The car will continue to move 2 m/s to the left because there are balanced forces acting on it.
