Question 3) The diagram is about the motion of an object in the xy plane: Overall the object starts at point A on the +y axis, moves in the-y direction until reaching the origin of coordinates where it makes a right angle turn and moves in the +x direction until reaching point D on the x-axis. The speed is not constant and we know more detail about the motion at only four points: When t-0.00s] it is at point A...
An object moves with respect to its reference (origin) following the following coordinates: x= 4.0m - (0.45m/s^2)t^2 y= (1.50m/s)t + (0.45m/s^3)t^3 a) Obtain the coordinates of the object, the displacement vector and the distance from the origin at t = 0.0 s and at t = 2.0 s. b) Obtain the average vehicle speed between t = 0.0 s and t = 2.0 s. c) If the instantaneous velocity at x of the object varies with time as follows: and...

Position and Velocity Vectors A squirrel has x- and y-coordinates {1.1 in, 3.4 m) at time t_1 = 0 and coordinates (5.3 m, -0.5 m) at time t_2 = 3.0 s. For this time interval, find (a) the components of the average velocity, and (b) the magnitude and direction of the average velocity. A rhinoceros is at the origin of coordinates at time t_1 = 0.
D Question 8 1 pts An object's velocity in the positive x-direction changes from 2.5 m/s to 8.7 m/s in 3.6 s A force of constant magnitude 18 N is acting on it. What is the object's mass in kg? Enter a number with two digits behind the decimal point.
A 5.71 kg particle-like object moves in a plane with velocity components vx = 16.9 m/s and vy = 51.5 m/s as it passes through the point with (x, y) coordinates of (9.95, -7.85) m. Just then, in unit-vector notation, what is its angular momentum relative to (a) the origin and (b) the point (-6.87, -6.87) m?

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...
