a) total displacement = Area under v-t curve
= 1*2 + (1/2)*2*2 +2*3 + (1/2)*2*3 - (1/2)*1*3
= 11.5 m
b) position = 10 + 11.5
= 21.5 m
c)
total distance travelled = 1*2 + (1/2)*2*2 +2*3 + (1/2)*2*3 + (1/2)*1*3
= 14.5 m
d)
at t = 1s,
a = (v2-v1)/(t2-t1) = (3-1)/(2-1) = 2 m/s^2
at t = 3s,
a = (v2-v1)/(t2-t1) = (3-3)/(4-2) = 0 m/s^2
at t = 5s,
a = (v2-v1)/(t2-t1) = (0-3)/(6-4) = -1.5 m/s^2
at t = 6.5 s
a = (v2-v1)/(t2-t1) = (-3 - 0))/(7-6) = -3 m/s^2

Given information: An object is moving with velocity (in feet per second) described by the function v (t) = 4t + 1. We will reason about the object's position function, 8 (t). Question 1 How much does the position change over the time interval (0,4) Answer with a number only (units are feet) 36 Question 2 Question: Think back to the total change theorem. What additional Information would allow us to find a(4), the object's position at time t =...

Time To the right is a graph of an object's position. Which sentence is the best interpretation of the motion of the object as shown by the graph? 2. A. The object is moving with a constant, non- zero acceleration. B. The object is not moving. C. The object...
Find an expression for the velocity function, v(t), of an object moving in a straight line if the object's acceleration function is 7 sin(t) +0.06 and the object's initial velocity is 155 ft/s. Then use your function to determine the object's velocity after 28 seconds.
If an object is thrown with a velocity of v feet per second at an angle of θ with the horizontal, then its flight can be modeled by, x = (v cos θ ) t and y = v (sin θ ) t - 16 t2 + h where t is in seconds and h is the object's initial height in feet above the ground. x is the horizontal position and y is the vertical position, and - 16 t2...
