Question

A ball moves along a 1D coordinate system with the following motion parameters at time t = 0 s: x0 = 7.7 m and v0 = 0 m/s. The ball has a constant acceleration of 1.2 m/s2 during the entire motion which occurs over a time of 3 s. Assume that an error in position of 9 % is acceptable in this application over the entire motion. How many rows N will be needed in the table to model the entire motion to within the required error even though you are leaving out the final term of 1/2 a (\Delta t\:Δ t)2 ) present in the exact position expression?

Answer #1

computer model displays the motion of a particle on a coordinate
system in real time. At time t = 0, the particle is at the origin
of the coordinate system and has velocity components vx = 0 and vy
= 5.2 m/s. The particle has acceleration components of ax = −4.4
m/s2 and ay = 0. (a) What are the x and y positions of the particle
at t = 6.0 s? x = m y = m (b) What...

A particle moves along a coordinate line so that its velocity
at time t is ?(?) = ?2 − 2? m/s. Find the total
distance travelled by the particle during the first 4 seconds.

A basketball is dropped from a walkway above Bartow Arena. It
falls from rest with a constant acceleration of 9.8 m/s2 until it
reaches the floor 3.1 seconds later. A physics class is modeling
the 1-D straight line motion as part of a class project They want
construct a simple, but accurate, data table using the following
equations: vi+1 = vi + a t and xi+1 = xi + vi t which are familiar
to you. Their instructor requires them...

One dimensional motion describes the changes in the position of
an object over time in terms of its displacement, velocity, and
acceleration in one direction. The motion in that
direction is independent of the displacement, velocity, and
acceleration associated with any of the perpendicular directions.
For example, the acceleration due to gravity near the surface of
the earth has a value of 9.8 m/s2, downward. This
affects the vertical motion of an object but has no effect on the
motion...

A projectile motion (i.e. cannon) can be modeled via the
following equations: x=u cosθ t y=-0.5 g t^2+u sinθ t Where: x:
Position of the cannonball after t seconds in the x-direction
(meters) y: Position of the cannonball after t seconds in the
y-direction (meters) u: Initial velocity of the cannonball (meters
per second) g: Acceleration due to gravity (meters per second
squared) t: Time (seconds) In this question, we are trying to see
the effects of the angle ϴ...
