1. Describe how you could use a textbook, a piece of paper, and desk to demonstrate Newton's First Law of Motion (with detail).
2. A student says, If action reaction forces cancel, then the net force must always be zero. How can anyone ever accelerate. Discuss the validity of this statement.
3. Identify a situation you have experienced that involves concepts from this chapter. make a question about it. (The chapter was on newtons 3 laws, f=ma, inertial/non inertial frames of reference, FBD diagrams and calculating net force acting on an object).
1. on a hot summer day in the state of washington while kayaking i saw several swimmers jump from a railroad bridge
A scuba diver is 48 m below the surface of a lake, where the temperature is 5°C. He releases an air bubble with a volume of 17cm3. The bubble rises to the surface.
Create algorithms appropriate for the situations: (a) x includes substantial Gaussian noise; (b) more measurements than latent variables (J > I); (c) fewer measurements than latent variables (J
A bullet with mass 20 grams and velocity 100 m/s collides with a wooden block of mass 2kg. What is the maximum compression of the spring
A monochromatic parallel beam of light of wavelength 633 nm is incident on totally reflecting plane mirror.angle of incidence is 60 degree. and number of photon striking per second is 1X10^19.calculate force exerted by light beam on mirror
A spring of constant k=3 lb/in. is attached to end A in such a way that its tension is zero when θ =- 0. If the rod is released from rest θ=0°, determine the angular velocity of the rod and the velocity of end B when θ = 0.
Sketch a force diagram for the desk.
A rock is thrown upward from the level ground in such a way that the maximum height of its flight is equal to its horizontal range R. At what angle is the rock thrown
A jogger accelerates from rest to 2.12 m/s in 3.34 s. A car accelerates from 24.1 to 38.6 m/s also in 3.34 s. Find the magnitude of the acceleration of the jogger
It takes the elevator in a skyscraper 4.5s to reach its cruising speed of 12m/s. What is the passenger's weight before the elevator starts moving
A rule of thumb used by travelers is that air pressure drops about 1 inch for every 1000-foot increase in height above sea level. Write a formula for the air pressure given by this rule of thumb.
A spring with a force constant of 1645 N/m is compressed 11.1 cm. Find the work done by the force compressing the spring
