Question

MOTION-II
What is the numerical ratio of average velocity to average speed of an object moving along a straight
line path? 11
A body moves with a velocity of 2m/s for 5s, then its velocity uniformly increases to 10m/s for the next
5 sec. Thereafter its velocity begins to decrease at a uniform rate until it comes to rest after 10s.
a) Plot a v-t graph and d-t graph for the motion of a body.
by Mark the portions of the graph when the motion is uniform and when it is non-uniform.
c) From the graph find the total distance moved by the body after 2s and 12s and in the last 10s.
Derive all the three equations of motion using graphical method.
A trolley while going down on an inclined plane has an acceleration of 2cms?
4 ans
What will be its velocity after 2s of the start?
A powerful motorcycle can accelerate from rest to 28 m/s in only 4s.​

Answer 1

Answer:

30 points anwer this is ....i need 20 followers fast then i will pick one from them and mark him brainiest i will mark u brainiest if you foloow mewill mark u brainiest if you foloow meGiven that 

y=sin−1x __(1)

then y"=?

from equation (1) to

y=sin−1x

on diff. and we get

dxdy=y′=1−x21

y′=1−x21

again diff and we get

y"=dxd(1−x2)−1/2

y"=−21(1−x)−21−1dxd(1−x2)

=2−1(1−x2)−23(0−2x)

=+22(1−x2)−23<

If y = sin^-1 x then find y''.A share of face value Rs. 20 has a premium of 30% means its market price is
