Answer 1 & 2 only. C. ApplicationDirections: Perform the following activities then answer the following questions on a separate sheet ofраper.1) Find two objects with the same size and shape but different masses. Drop them from the sameheight to a flattened clay on the floor. Compare the impact of the object with greater mass to theobject with lesser mass to the flattened clay on the floor. How do their masses contribute to theirenergy?2) Find two identical marbles with the same mass and texture, and an empty plastic bottle. Strike theempty bottle with the two marbles in varying speed. The first marble has slower speed while thesecond marble is in faster speed. Differentiate the impact of the two different marbles on theempty bottle. How would you relate the energy of the speed of the two different marbles?3) Suppose you are to go upstairs, and you are to choose between two stairs. One staircase is longerthan the other. Which will you choose: the shorter or the longer staircase? Why?

(a) During an ice skating performance, an initially motionless 80.0-kg clown throws a fake barbell away. The clown's ice skates allow her to recoil friction-lessly. If the clown recoils with a velocity of 0.500 m/s and the barbell is thrown with a velocity of 10.0 m/s, what is the mass of the barbell? (b) How much kinetic energy is gained by this maneuver? (c) Where does the kinetic energy come from?

Check Your Understanding Suppose you have a macroscopic salt crystal (that is, a crystal that is large enough to be visible with your unaided eye). It is made up of a huge number of unit cells. Is the center of mass of this crystal necessarily at the geometric center of the crystal?
In Section 1.4, we considered the collision of a karate expert’s hand with a concrete block. Based on the graphs in Figure 1.31, the initial downward speed of the fist with mass 0.75 kg is about -13 m/s and the collision time is approximately 25 ms. Find the impulse and the average force exerted on the block by the fist during the collision.
The velocity of a 10-kg object is given by v=5t2i(7t+2t3)j, where if t is in seconds, then v will be in meters per second. a. What is the net force on the object as a function of time? b. What is the momentum of the object when t = 15.0 s?

A crate of mass M is initially at rest on a frictionless, level table. A small block of mass m (m M) moves toward the crate as shown in Figure P10.31. Later, the block and crate are stuck together and are moving with some final speed. The momentum of the blockcrate system is the same both before and after the collision. Is the magnitude of the change in momentum of the crate greater than, less than, or equal to the magnitude of the change in the momentum of the block? Explain. FIGURE P10.31
You are part of a team in an engineering class that is working on a scale model of a new design for a life vest. You have been asked to find the mass of a piece of foam that will be used for flotation. Because the piece is too bulky to fit on your balance, you break it into two parts. You measure the mass of the first part as 128.3 0.3 g and the second part as 77.0 0.3 g. a. What are the maximum and minimum values for the total mass you might reasonably report? b. What is the best estimate for the total mass of the foam? Hint: Propagation of uncertainty is described in Appendix A.
