An object moves with constant acceleration. At t = 2.50 s, the position of the object is x = 2.00 m and its velocity is v = 4.50 m/s. At t = 7.00 s, v = -12.0 m/s. Find: (a) the position and the velocity at t = 0; (b) the average speed from 2.50 s to 7.00 s, and (c) the average velocity from 2.50 s to 7.00 s.
Please explain reasoning and show all conversions and units for each equation, Thanks The position of a particle moving along the x axis is given in centimeters by x = 9.75 + 1.50t3, where t is in seconds. Calculate (a) the average velocity during the time interval t = 2.00 s to t = 3.00 s; (b) the instantaneous velocity at t = 2.00 s; (c) the instantaneous velocity at t = 3.00 s; (d) the instantaneous velocity at t...
Please answer all my questions correct ! Please answer all my questions correct ! Please answer all my questions correct A hot air balloon rises vertically at a constant speed of 12.0 m/s. A passenger accidentally drops his camera from the railing when it is 18.0 m above the ground. If the balloon continues to rise at the same speed, how high is the railing when the camera hits the ground? (Hint: First find the velocity of the camera when...
7:32 0 . 18% 5 Col20628 il y Pow To (a) The graph below plots the position versus time for an object moving in one dimension along the x direction. What is the speed (magnitude of velocity) of the object at. The graph plots position vs. time, not velocity vs. time. To find velocity, think about the definition of instantaneous velocity and how it is related to position. Notice the graph is a straight line from .. . Can you...
Draw graph for position, velocity, and acceleration based on the word description. how does the position graph look like, same with velocity and acceleration according to the description? Thank you Case 13 Word description of the motion: At some position x > 0 the object is traveling in the negative x-direction and slowing down at a constant rate The object momentarily comes to rest at some position x <0. Immediately it begins to speed up again at a constarnt rate...
