A 0.02 kg ball is flying horizontally at 120 mps. It is struck by a force at 400 as shown. The impulse graph is given. What is the final velocity of the ball? please show complete fbd and solution
1. a) A steel ball is dropped from a building's roof and passes a window, taking 0.13 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.13 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 1.93 s. How tall is the building? b) A basketball player grabbing a rebound jumps 74.1 cm vertically. How much total time (ascent and descent) does the player spend in the bottom 10.3 cm? Do your results explain why such players seem to hang in the air at the top of a jump?
A weight is attached to a spring suspended from a beam. At time t = 0, it is pulled down to a point 8 cm above the ground and released. After that, it bounces up and down between its minimum height of 8 cm and a maximum height of 24 cm, and its height h(t) is a sinusoidal function of time t. It first reaches a maximum height 1.4 seconds after starting. (a) Follow the procedure outlined in this section to sketch a rough graph of h(t). Draw at least two complete cycles of the oscillation, indicating where the maxima and minima occur. (b) What are the mean, amplitude, phase shift and period for this function? (Use a phase shift with an absolute value less than the period.) mean 16 amplitude 8 phase shift ___ period 2.8 (c) Give four different possible values for the phase shift. (Enter your answers as a comma-separated list.) _______ (d) Write down a formula for the function h(t) in standard sinusoidal form; i.e. as in the…

1. If the initial position and initial velocity of a vehicle are known and a record is kept of theacceleration at each instant, can you compute the vehicle's position after a certain time fromthese data? If so, explain how this might be done.
One morning, Connie walks from her house to go to a store that is 500 ft, S 40o W from her house. She starts walking 120 ft, SW; then continues walking 100 ft, 10o S of E; then sees a friend who is 700 ft, 30o N of E from where she is. What is her friend’s location, (magnitude and direction) relative to her house? (Ans. 667.54 ft, 21.79o N of E) From her friend’s location, how far and in what direction should Connie walk to finally get to the store? (Ans. 1133.08 ft, 33.83o S of W)
In the kinematic diagram, the limb dimensions are given below, in the arm slide mechanism, the actuating limb angular position is (theta)θ12 = 600 and the speed of the mechanism is given as (thetadot)θ'12 = 50 rad / s . Do the following operations respectively. Find S'13, (thetawithdot)θ'14 by analyzing velocity.
There is a collision betwen two dry ice A and B. In total, there combined mass equals 300g(Ma=Mb=300g). The collision takes place using magnets and is captured using a strobe light that flashes 10 times a second. Addtionally Puck B is initially at rest. Now with ths information listed solve for the variable before and after the collision with the charts below.

PROBLEM 3: POWER AND EFFICIENCY PLEASE HELP ME WITH MY ASSIGNMENT - Solve the problems on a clean sheet of paper. Follow the Given-Required-Analysis-Solution-Summary of Answers format. Make sure to include all pertinent solutions. - Round your final answers to three (3) decimal places. For example, if you calculated an answer to be “9.80665” it should be expressed as “9.807”. At the instant shown, point P on the cable has a velocity vp = 12 m/s which is increasing at a rate of ap=6m/s2. Determine the power input of motor M at this instant if it operates with an efficiency of 0.8. The mass of block A is 50 kg.
