Displacement=x-0=x (assuming the journey started at t=0)
time=t
x=ut+1/2 at^2
u=initial velocity=0
acceleration=a=((x-ut)*2)/t^2
a=(13.6t+17t^2)/t^2
a=17+13.6/t
Answer:
6.41m/s2
Explanation:
unit conversion:
78 rev/min = 78rev/min * 2π rad/rev * 1/60 min/sec = 8.168 rad/s
12 in = 12 in * 2.54cm/in = 30.48 cm = 0.3048 m
So the record accelerate from rest to 8.168 rad/s, its (assuming constant) angular acceleration would be
From here we can calculate the angular velocity of the bug at t2 = 1.5s
Its centripetal acceleration would then be
Answer:
it take blood to the lung so the blood could be oxygenated

Answer:
C. L
Explanation:
Given that
Displacement of the object is given as
x = A sin(2 n f t)
We know that
Quantity Dimensions
Length/Amplitude L
Distance /Displacement L
Time T
Velocity LT⁻¹
Acceleration LT⁻²
Area L²
Mass M
Frequency T⁻¹
Given that x is the displacement that is why the dimensions of the displacement will be L.
Now by balancing the dimensions both sides ,the dimensions of the A will be L.
C. L
