3. A train boxcar traveling in the positive x-direction with a velocity, u 10.00 m/s R, passes directly in front of an observer on a stationary platform. At the precise moment the boxcar passes the observer, a particle is launched from the bottom, left corner of the boxcar with an initial speed, vo' 8.00 m/s at an angle of 0 30.0° above the horitonatal according to an observer on the boxcar (shown below left). Immediately following the launch, the boxcar...
A particle P travels with constant speed on a circle of radius r = 2.40 m (see the figure) and completes one revolution in 20.0 s. The particle passes through O at time t = 0. At t = 5.00 s, what is the particle's position vector? Give (a) magnitude and (b) direction (as an angle relative to the positive direction of x. At t = 7.50 s, what is the particle's position vector? Give (c) magnitude and (d) direction...
A satellite in outer space is moving at a constant velocity of 21.0 m/s in the +y direction when one of its onboard thruster turns on, causing an acceleration of 0.330 m/s2 in the +xdirection. The acceleration lasts for 45.0 s, at which point the thruster turns off. a) what is the direction of the satelites velocity when the thruster turns off (anwser in meters per second) B) what is the direction of the satelites velocity when the thruster turns...
(10%) Problem 5: A ball with an initial velocity of 5.5 m/s and mass 2.5 kg moves at an angle 68° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 68° above the horizontal, moving in the opposite direction with the same speed. See the figure. е 4 What was the magnitude of the impulse delivered by the wall, in kilogram meters per second? Grade Summary Deductions Potential 100% E sin cos...
1) Consider a pendulum of constant length L to which a bob of mass m is attached. The Q6. pendulum moves only in a two-dimensional plane (see figure below). The polar frame of reference attached to the bob is defined by er,ce where er is the unit vector orientecd away from the origin and e completes the direct orthonormal basis. The pendulum makes an angle 0(t) between the radial direction and the vertical direction e(t) The position vector beinge ind...
1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...
