Answer:
The value of the constant k is 2
Explanation:
We have the equation of the velocity = kt² , where k
is constant and t is the time in second
The particle's position at = 0 is
= -9 m
The particle's position at = 3 s is
= 9 m
We need to find the value of the constant k
The relation between the velocity and the displacement in a particular
time is x =
Remember in integration we add power by 1 and divide the expression
by the new power
→ x =
c is the constant of integration to find it substitute the initial value of x
and t in the equation of x
→ = 0 ,
= -9 m
→ -9 = k (0)³ + c
→ -9 = c
Substitute the value of c in the equation of x
→ x = k t³ - 9
To find k substitute the values of = 3 s ,
= 9 m
→ 9 = k (3)³ - 9
→ 9 = (27) k - 9
→ 9 = 9 k - 9
Add 9 to both sides
→ 18 = 9 k
Divide both sides by 9
→ k = 2
<em>The value of the constant k is 2</em>
Answer:
The value is
Explanation:
From the question we are told that
The speed of the marathon runner is
The distance from the distance from the finish is
The speed of the bird is
Generally the time taken for the runner to reach the finish is mathematically represented as
So the distance covered by the bird is
