Q Next diagram shows relationship between aelocity and time of a body moving along shown path. Let me see physical touches in your answer, not just mathematical notes. O Find the average acceleration of the object during the time intervals (0-5) . (5-15) s (0-20) s i) Find the instantaneous acceleration at 2. 10s, 18s (ii) Find the displacement between (10-20) s. v (m/s) 8 6 4 2 I (s) 20 15 -2 -4 -6 -8 l

You measure the motion of a dynamics cart using a motion sensor.  You then plot the cart’s position vs. time and velocity vs. time.  The best way of finding the average acceleration of the cart is to find: a. the y-intercept of the position vs. time plot. b. the y-intercept of the velocity vs. time plot. c. the slope of the position vs. time plot d. the slope of the velocity vs. time plot. e. none of the above

Lisa runs 1.5 km along a straight path and then turns and runs 2.4 km in the opposite direction. She then turns back and runs 700 m in the original direction. Let Lisa’s original direction be the positive direction. What are the displacement and distance, in km, she ran? * A. Displacement is 4.6 km, and distance is -0.2 km. B. Displacement is -0.2 km, and distance is 4.6 km. C. Displacement is 4.6 km, and distance is +0.2 km. D. Displacement is +0.2 km, and distance is 4.6 km.

A small object moves along the x-axis with acceleration a₂ (t) = -(0.0320 m/s³) (15.0 s-t). At t=0 the object is at x = -14.0 m and has velocity Voz = 8.20 m/s. Part A What is the x-coordinate of the object when t = 10.0 s? Express your answer with the appropriate units. x= μА Value 4 m ? X Incorrect; Try Again; 2 attempts remaining

2. A jet plane has a takeoff speed of vtakeoff = 73 m/s and can move along the runway at an average acceleration of 2.4 m/s2. The runway is 1.2 km. Write out the 3 Kinetic equations. a. b. Write out the values of initial position, initial velocity, and acceleration. How many seconds will it take for the plane to reach takeoff speed? с. d. How far will the plane have to travel to get to takeoff speed? will the plane be able to get to take off before it gets to the end of the runway? е.

When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.
