DQuestion 4 The graph below describes the relationship between velocity and time for a moving object. Velocity vs. Time v (m/s) 3 t(s) 0123 11 -2 What is the object's acceleration at time t =8 s? 12 m/s? O Omie

Can this be explained with a lot of detail in order to understand.

1. How long did the car remain in the air? 2. How fast did the car drive off the cliff?

Which of these is an example of high precision? a. An archer hits the bulls-eyeb. A student correctly calculates the acceleration due to gravity to be 9.8ms2c. An archer hits the same spot on the target three times in a rowd. A student tries to throw a pencil into the garbage can and makes it ine. A student correctly calculates the mass of an object to be 54kg

I need the answer as soon as possible

Keeping the total mass constant 1.  Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? 2.  Did a change in the net force produce a change in acceleration by the same factor? Do your results agree with Newton’s 2nd Law? 3.  Make a plot of Net Force vs. Experimental Acceleration and draw the best fitting line.

I need steps to solve this to understand it

Diagnostic/Introductory Activity Unit 3, Lesson 4 The graph shows the results of a 200 m race run by Sarah and Hasib. Examine the graph to answer the questions below. 200mRace 250 200 150 Sarah - Hasib 100 50 10 15 20 25 30 Time (seconds) 1. Who won the race? How can you tell? 2. How does the line of the faster runner compare to the line of the slower runner? 3. At what time did the winner finish the 200m race? LO

I PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?

please send correct answer

I am stuck with this problem please help to solve it

Vernier app calculations are provided, please draw the acceleration, position, velocity time graphs from vernier numbers, excel sheet numbers provided, questions to answer a) Compare and comment on the velocity vs time graph from vernier app and the excel spreadsheet b) compare and comment on the acceleration vs time curve vs the excel spreadsheet  c) can you estimate the uncertainties for the position, velocity and acceleration d) explain the motion of the cart based on the position, velocity and accerlation graphs  e) does your cart move with constant acceleration during any part of this experiment? when?  f) estiamte the acceleration during this portion of the experiment from the slope of the velocity-time graph. Compare your result with the average value of the acceleration determined from your acceleration-time graph. You don't need to be really presice here; a rough comparison is all that is needed    Data points from vernier are:  Time:  1) 02) 0.66666666666666663)…

Task 3 As a part of your role in the motion and dynamics analysis department, you have been asked to design a mission consists of airplane and boat. The mission target is to deliver a package by the airplane that must be picked by the boat. You must provide two analysis steps to solve the problem: 50 m/s Package Figure.2: Package of emergency supplies Part 1 • The airplane traveling horizontally at 50 m/s • The airplane is 150 m above the sea 9. Write the displacement vector r* as a function of time and find by calculus the acceleration vector a". 10. Compare the acceleration vector you have got from Part.9 with the known projectile motion values. 11. What is your student ID?

4) Activity 5: Check for Understanding (5 mins) Student Engagement (SE) Think-Pair-Share Solve the problem. 1. You are working as a delivery person for a dairy store. In the back of your pick-up truck is a crate of eggs. The dairy company has run out of bungee cords, so the crate is not tied down. You have been told to drive carefully because the coefficient of static friction between the crate and the bed of the truck is 0.6. You are not worried, because you are traveling on road that appears perfectly straight. Due to your confidence and inattention, your speed has crept upward to 45 miles per hour. Suddenly you see a curve ahead with a warning sign saying, "Danger: unbanked curve with radius of curvature 35 m". You are 15 m from the beginning of the curve. What can you do to save the eggs: (a) take the curve at 45 mi/h, (b) brake to a stop before entering the curve to think about it, or (c) slow down to take the curve at a slower speed? Discuss these options in your group and…
