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...
3. If the acceleration of an object moving along the x axis is described by a(t)=-0.4 m/s2. If the initial speed of the object is 5.4 m/s when it is at -2.0m, find the average velocity of the object between 0 and 5.00 sec
A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
(ii)(a) An object is moving with constant acceleration in 1D (along a straight line), what is its position x(t) as a function of time, given its initial position xo, initial velocity vo and acceleration a? (b) How do you derive its velocity as a function of time from x(t)? (c) Why is the funciton of x(t) the key for predicting eclipses and hurricanes?
An object experiences a constant acceleration of 2.0 m/s^2 along the -x acid for 2.7s, attaining a velocity of 16 m/s in a direction 45 degrees from the +x axis . Find the initial velocity vector of the object.
6) An object is originally moving and a constant acceleration of 8 m/s2 is applied to it +x direction which causes it stop after 2.0 seconds. What was the magnitude of the initial velocity in m/s?
Find magnitude of velocity and acceleration at t=1 Part A Learning Goal To be able to calculate position, velocity, and acceleration of an object in curvilinear motion using a rectangular coordinate system. A car drives on a curved road that goes down a hill. The car's position is defined by the position vector An object's motion can be described along a path represented by a fixed x, y, z coordinate system. In such a system, the position vector, r, is...
.4j A particle is moving with a velocity of U 7.4 The particle's acceleration is 0.18i-0.9j. +3 S At this instant the particle is moving along part of a curved path which can be estimated as a circle of radius R. This curving is provided by the component of acceleration perpendicular to the motion of the particle. What is the magnitude of the component of acceleration perpendicular to velocity?
