A gray kangaroo can bound across a flat stretch of ground with each jump carrying it 10 m from the takeoff point. you may want t

Stells [14]

<u>Answer:</u>

Takeoff speed of Kangaroo = 12.91 m/s

<u>Explanation:</u>

The distance reached by Kangaroo = 10 meter

Angle at which it jumps = 18°

The motion of Kangaroo is like a projectile, the distance traveled is the range of projectile.

Range of projectile = Time taken for the projectile to reach ground* Horizontal velocity

Time taken for the projectile to reach ground:

Time taken = Two times of the time taken for the projectile to reach maximum height

Time taken for the projectile to reach maximum height = Vertical speed / Acceleration = u sin θ/g

Time taken for the projectile to reach ground = 2 u sin θ/g

So Range of projectile = $ucos\theta*\frac{2usin\theta}{g} =\frac{u^2sin2\theta}{g}$

We have Range = 10 meter, θ = 18⁰

Substituting

$10=\frac{u^2sin(2*18)}{9.8}\\ \\ u^2= 166.73\\ \\ u=12.91 m/s$

Takeoff speed of Kangaroo = 12.91 m/s

Which of the following activities would be fueled by adenosine triphosphate (ATP) and the phosphagen system?A. 400-meter sprintB

Ksenya-84 [330]

Answer:

C

Explanation:

The Phosphagen System or Adenosine TriPhosphate - Creatine Phosphate (ATP-CP) is available in the muscles in a limited quantity, hence the amount of energy that is released through Phosphagen system is limited.

As a result the phosphagen stored in the muscle is exhausted vigorously and can only be used for activities which require very high energy for a very short duration of time.

A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5m/s/s. Determine the mass of the encyc

Neko [114]

A=5m/s
F=15N
by the formula, F = m × a
15N = m × 5m/s
m = $\frac{15}{5} 
$
By simplification(division),
m = 3
Thus, mass of the Encyclopedia will be 3kgs.

All the Best. :D
