8a.(15)Answer the following questions based on the F-t diagram. a. What would be the Impulse imparted to an object?...
Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force ΣF⃗ acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse J⃗ is a measure of both these effects. For a constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse is a vector pointing in the same direction as the force vector. The units...
The impulse shown is applied to a 2.0 kg object. If the object is initially at rest, what is the velocity after the force is applied? FN)F 18 000 N 20 000 15 000 10 000 5 000 t(ms
MEC311 Term Test, 2019w 2. 145%) This problem is about using work-energy and impulse-momentum principles. You must answer according to the notations and coordinate systems set up for you Answers based on other coordinate sysfem or notations will not be marked. Consider a sticky ball of weight Ws 0.1 [lb] located on an incline of angle 0-30-deg. The ball is initially placed on top of a compressed linear spring of spring constant k 10 [lb/ft]; see figure. It is released...

Thank you in advance! 15. (N) 23). A 5 kg object that moves along the x-axis is acted upon by a net force that varies with position as shown in the figure at right. The kinetic energy of the particle at x= -2 m...
Impulse F* At is an invariant for all observers moving co-linearly with a lab frame observer A moving observer at an angle relative to the lab frame would report a 2-dim collision with the x component of F" At being the invariant with x-axis as the lab frame axis 1 (from recitation-08) А 10 kg composite object traveling with velocity 29 rn/s, 0 degree) had an internal disturbance such that the composite object was split into Object-A with 3 kg...

23, 24, 28 Sketch the free-body diagram of a baseball (a) at the moment it is hit by the bat. and again (b) after it has left the bat and is flying toward the outfield. Ignore air resistance. Arlene is to walk across a "high wire" strung horizontally between two buildings 10.0 m apart. The sag in the rope when she is at the midpoint is 10.0". as shown in Fig. 4-47. If her mass is 50.0 kg. what is...
Answer the following questions based on the v-t diagram for t = 0 - 10 seconds. What is the maximum velocity? When is the magnitude of the acceleration greatest? What is the acceleration at t = 2.4 s? At what time(s) is a = 0? Use the diagram to approximate the distance traveled between t = 1 and t = 3 seconds.
please answer with showing work Section 2: Calculation Questions (8 pts. each part) 1. A block with mass of m, = 5 kg is sliding across a frictionless table when it strikes a second mass with me = 3 kg, that is initially at rest. After the collision, the two masses stick and move off together with a speed of v= 1.5 m/s. The two masses then slide off the table and fall together 2 meters to the ground. a)...
Question #4 20 points total):The following net force acts on a 4.00-kg object F(2x2 N)t+ (12 N) The object starts from rest and is moved from coordinates (O.00 m, 1.00 m) to (2.00 m, 3.00 m). Part A (10 poimts): Find the total work done on the object Part B (10 points):Find the final speed of the object
