Suppose an object moves along a line at 10 m/s for 0sts2 s and at 16 m/s for 2

6. a) Describe the motion pictured by the v-vs.-t graph shown. v(m/s), + 6 7 H t(s) 4.

Pls help ASAP

pls. answer with FBD pls. A car accelerates uniformly from zero to 10m/s2 in 6 seconds starting from rest. During the next 3 seconds, the car decelerates at a constant rate of 2m/s2. Compute the total distance traveled after 9 seconds.

The goal of this lab is to draw conclusions about motion graphs and practice graphing motion. mtroduction: Motion graphs are important to understand how objects are moving. In this lab activity, we will create motion graphs from motion diagrams and from description situations. O8 ) = 1 s こ=} as 9 =1 8. Feet 4. 12 FIGURE 1-9 Motion diagram of a skateboarder, showing position and time. Part 1: Motion Diagrams Basics Instead of graphing from a data table, we will be graphing from a motion diagram. The diagram below shows Harold running from 0m to 100m on the track. He is moving along the positions, shown on the number line and his time at each position is tracked above him. Using these values, first create a data table. Then graph the motion (using time on the x and position on the y). Lor on Ceu 0 10 20 30 40 50 60 70 80 90 100 0 10 S0

4) While Prof. K. was stuck in airport over break, she saw someone riding a Modobag (the world's first motorized carry-on luggage) and immediately ordered one off Amazon. Once it got delivered, she took it for a test ride up the hill between the Student Union and the football stadium. Prof. K. started traveling with an unknown initial velocity and came to a complete stop after 25 ft. a) Clearly draw coordinate systems for Prof. K. travelling up the hill. Write out the necessary transformation arrays. b) Draw an FBD and IRD for the system. c) Rolling friction is a function of normal force, just like regular friction would be, therefore Frolling=Crr*N. Develop a symbolic equation for the friction force, Frolling, of the bag in terms of the other forces on the FBD (i.e. develop an expression for "N") d) The coefficient of rolling resistance, Crr between the wheels and the ground is equal to 0.0295. The combined weight of Prof. K. an her packed Modobag is 180 Ibs. and the angle 0 = 15°.…

Question 4: A car moves with a constant accelaration of "a" from the initial values of t=0s, xo (position) and V. (velocity). The equation of motions define as followings. Please draw the graphs of displacement, velocity and accelaration changes by time. 9 = 0, + at; x = x, + 0,t +at?

The motion of a person as seen by another person is described by the equation v=-3.0m/s+0.5m/s^2t. Draw a motion diagram. draw a motion potion vs time graph draw a motion velocity versus time graph draw a acceleration vs time graph say everything you can about this motion and what happens to the person when his speed becomes zero.
