i. Sketch the velocity vs time graph for the object’s motion described below. Mark all labels and values appropriately. The object at rest starts to move from east to west. • Between 0-4 seconds it moves with an acceleration of 2 ??−2 • Then with a constant velocity for 4-10 seconds. • Finally with a deceleration of 2 ??−2 the object comes to rest. ii. Find the velocity of the object at t= 4 secs and calculate how long the object decelerates before it comes to rest.

Expert Solution

in order to draw the velocity vs time graph we have to find the velocity of the object at t = 4s . Initially the object was rest then accelerate with acceleration of 2 m/s². So we can find the velocity after 4 s and the object moves with constant velocity upto 10 s and then it decelerate. So we can find the time when it stops.

A) Sketch the position vs. time graph for the following motion. Starting at 0.5m from the detector, you moved away at a constant velocity of 3 m/s for 2 seconds, then stood still for 1 second and then walked toward the detector for 1 second at a velocity of 4m/s after which you stood still for 3 seconds. B) sketch the velocity vs. time graph for the above description.

For the following described motion, fill in the position/time, a velocity/time, and acceleartion/time graphs on the grids provided. Show your work for calculating exact positions, velocities and times in the space below. The graphs should be excact. 1. The particle begins at rest at the origin and undergoes an acceleartion of 1m/s for 1s. 2. The acceleration of the particle then changes instantly to zero for 2s. 3. The parrticle then instantly undergoes an acceleration of minus 2m/s for 1s....

Draw a position-vs-time, velocity-vs-time, and acceleration-vs-time graph for each of the following objects: 1. A car traveling in a straight line at a constant speed. 2. A ball rolling down a hill, getting faster as time goes by. 3. A rock that is tossed straight up in the air before coming back down to its starting point.

1. Does adding more mass change a slope of the angular velocity vs time graph? why? 2. Does changing the radius the string is wrapped around change the slope of the angular velocity vs time graph? If so, how? 3. instead of mass, ehich quantity do we talk about in twrms of rotational motion? write down common formula.

Write the following quadratic function in standard form and then sketch its graph. Clearly mark on the graph the vertex and all intercepts. f(x)=-2x^2+6x+15 Note: if you could include step by step explanations so I’ll be able to understand the process and learn this concept that would be great!!

Show the qualitatively correct position versus time graph and the matching velocity versus time graph for an object that passes through the point X0 = -1 m at t0 = 0 s, and speeds up in the negative X-direction until it reaches a constant speed at tA. Between tA and tB, the object maintains this speed. At tB the object slows down and makes a momentary stop at tC, and immediately resumes the motion in the opposite direction (show a...
