An object of mass 4.15 kg undergoes an acceleration of 3.5 m/s^2 for a period of...

An object of mass 4.15 kg undergoes an acceleration of 3.5 m/s^2 for a period of 7.0 seconds. It then undergoes an acceleration of -4.2 m/s^2 for a period of 18.0 seconds. If the initial velocity of the object is 4.01 m/s and it first experiences the acceleration when it is at the origin, plot by hand on graph paper (to scale) the force, velocity, and position graphs as functions of time. Explain why your graphs look the way they...

(a) A fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass. If the proportionality constant is defined to have no dimensions, determine the dimensions of force. (Use the following as necessary: M, L, and T.) (b) The newton is the SI unit of force. According to the results for (a), how can you express a force having units of newtons using...

Consider the following descriptions of the vertical motion of an object subject only to the acceleration due to gravity. (Note: the acceleration due to gravity is 9.8 m divided by s squared.) a. Find the velocity of the object for all relevant times. b. Find the position of the object for all relevant times. c. Find the time when the object reaches its highest point (What is the height?) d. Find the time when the object strikes the ground. A...

Free Fall on Different Worlds Objects in free fall on the earth have acceleration ay=−9.8m/s2ay=−9.8m/s2. On...

Free Fall on Different Worlds Objects in free fall on the earth have acceleration ay=−9.8m/s2ay=−9.8m/s2. On the moon, free fall acceleration is approximately 1/61/6 of the acceleration on earth. This changes the scale of problems involving free fall. For instance, suppose you jump straight upward, leaving the ground with velocity vivi and then steadily slowing until reaching zero velocity at your highest point. Because your initial velocity is determined mostly by the strength of your leg muscles, we can assume...

B.What will the acceleration be if the object's mass is halved? C. What will the acceleration be if the force and the object's mass are both halved? D. What will the acceleration be if the force is halved and the object's mass is doubled?

A small object begins a free-fall from a height of ?=87.5 mH=87.5 m at ?0=0 st0=0 s. After τ=2.25 sτ=2.25 s, a second small object is launched vertically up from the ground with an initial velocity of ?0=41.4 m/sv0=41.4 m/s. At what height from the ground will the two objects first meet?
