Two identical peaches, Peach 1 and Peach 2, fall from a cliff at time t=0t=0t, equals, 0 from the same height. Peach 1 is droppe

d from rest, while Peach 2 is thrown horizontally.
Which graph best describes the vertical displacement of Peach 1 and 2 over time?
Assume the origin of the coordinate system to be the cliff edge.

Choose 1 answer:

(Choice A)
A
A graph is shown with the vertical axis labeled y and the horizontal axis labeled t. Two lines both start at the origin and slope downwards to the right. The solid line is straight while the dashed line has downward concavity.

(Choice B)
B
A graph is shown with the vertical axis labeled y and the horizontal axis labeled t. Two lines both start at the origin and slope downwards to the right. The dashed line is straight while the solid line has upward concavity.

(Choice C)
C
A graph is shown with the vertical axis labeled y and the horizontal axis labeled t. Two lines both start at the origin and slope downwards to the right with downward concavity. Both lines are coincident.

(Choice D)
D
A graph is shown with the vertical axis labeled y and the horizontal axis labeled t. Two lines both start at the origin and slope downwards to the right with downward concavity. The solid line is shallower than the dashed line.

(Choice E)
E
A graph is shown with the vertical axis labeled y and the horizontal axis labeled t. Two lines both start at the origin and slope downwards to the right with upward concavity. The dashed line is shallower than the solid line.

Answer:

   The value is \vec  B  =  2, -3

Explanation:

Looking at the graph in the diagram we see each unit is equal to 1 both in the x axis and in the y- axis

  Now the value of B along the x axis is  

         B_x = 2

and along the y axis the value  is  

        B_y  = -3

Hence the vector B is

     \vec  B  =(B_x  , B_y)=  ( 2, -3)

How to find instantaneous velocity physics?
evablogger [386]
You should have the velocity as a function of time either given explicitly or implicitly (a graph)

v = ds/dt  (differentiating the position vector)

integrating the acceleration.

you can use impulse or work and energy principle and also newton law of motion to find acceleration then velocity


NOT SURE IF THAT WHAT YOU WANT.

A particle moving along the x-axis has its position described by the function x=(3.00t3−1.00t 2.00)m where t is in s. at t = 4.0
prohojiy [21]
X =(3.00x4.00 x3-1.00t x 2.00) x m

x= (12.00x3- 1.00 x2.00) x m
x= 36.00 -1.00 x 2.00) x m
x = (36.00 -2.00) x m
x =( 34.00) x m
x =34.00   times m
