are you sure it's Thaivan or Taiwan. If it's Taiwan than it's Taipei.
Hope this help :))
Given:
u = 0, initial speed (sprinter starts from rest)
v = 11.5 m/s, final speed
s = 15 m, distance traveled to attain final speed.
Let
a = average acceleration,
t = time taken to attain final speed.
Then
v² = u² + 2as
or
(11.5 m/s)² = 2*(a m/s²)*(15 m)
a = 11.5²/(2*15) = 4.408 m/s²
Also
v = u +a t
or
(11.5 m/s) = (4.408 m/s²)*(t s)
t = 11.5/4.408 = 2.609 s
Answer:
The average acceleration is 4.41 m/s² (nearest hundredth).
The time required is 2.61 s (nearest hundredth).
The substance is DNA and it would be found in the nucleus.
I think that mechanism is called a <em>"lens turret"</em>.
Force = mass*acceleration so
3.6*2.5 =9 Newtons
