Answer:
Equation Symbol breakdown
v = r ω v = r \omega v=rω v v v is linear speed, r is radius, ω is angular speed.
T = 2 π ω = 1 f T = \dfrac{2\pi}{\omega} = \dfrac{1}{f} T=ω2π=f1 T T T is period, ω is angular speed, and f is frequency
Answer:
Answer
Let the initial velocity of the object = u
Let the object is moving with uniform acceleration, a.
Let object reaches at point B after time, t and its final velocity becomes, v
Draw a line parallel to x-axis DA from point, D from where object starts moving.
Draw another line BA from point B parallel to y-axis which meets at E at y-axis.
The distance covered by the object moving with uniform acceleration is given by the area of trapezium ABDO
Therefore,
Area of trapezium ABDOE =
2

× (sum of parallel sides + distance between parallel sides)
Distance(S)=

(DO+BE)×OE
S=

(u+v)×t(i)
we know that,
a=
t
v−u
from above equation we can say,
t=
a
v−u
(ii)
After substituting the value of t from equation(ii) in equation (i)
S=
2a

(u+v)(v−u)
2aS=(u+v)(v−u)
2aS=v
