Answer and explanation:
Given : The position of an object moving along an x axis is given by where x is in meters and t in seconds.
To find : The position of the object at the following values of t :
a) At t= 1 s
b) At t= 2 s
c) At t= 3 s
d) At t= 4 s
(e) What is the object's displacement between t = 0 and t = 4 s?
At t=0, x(0)=0
At t=4, x(4)=14.24
The displacement is given by,
(f) What is its average velocity from t = 2 s to t = 4 s?
At t=2, x(2)=-1.76
At t=4, x(4)=14.24
The average velocity is given by,
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, If the given equation is and
.
Step-by-step explanation:
The given is,
...............................(1)
...............................(2)
Step:1
Solution can be obtained by Elimination method,
Equation (1) is multiplied by (-1) ( Eqn (1) × -1 )
..............................(3)
Substrate the equation (1) and equation (3),
( - )
we can cancel the minus because it is available in both sides,
x = 4
From the value of x, Equation (2) becomes,
(Value of y in terms of x)
Where, x = 4
Step:2
Check for solution,
.....................................(2)
Substitute the values of x and y,
4 + 4 = 8
8 = 8
Result:
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, where x=4. If the given equation is and
