do an experiment to find the acceleration and velocity of an object.
Plz answer
Answers
Initial velocity of object (u) = 15m/s
Final velocity of object (v) = 10 m/s
Time taken (t) = 2 seconds
As, we know formula for acceleration is -
(v-u)/t
So, Acceleration = (10-15)/2
= -5/2
= -2.5 m/s²
=-2.5 m/s²

Step-by-step explanation:
Presently, There will act one power called as Component of the Weight along the Incline which is given by the Relation,
mgsinθ,
where θ is the edge which the slope makes with the surface or Angle of the Incline.
Presently, If there will be no erosion and the article is moving along the slope, Then,
Power =mgsinθ
mama =mgsinθ
a=gsinθ
This case is legitimate when the edge of the Incline is more noteworthy than the point of rest, implies the item is moving with no the reason or acing of the power.
However, in some cases when the item does not moves without the activity of power, I imply that edge of rest is more prominent than the edge of the grade, at that point we have to apply the power so the article can move at that point,
Power connected =mgsinθ
a=gsinθ
The cases will be changed when the erosion is included.
Presently, For speed, It can be find by utilizing the condition of Motions. Time, Distance or beginning speed and so on must be given if question will be asked identified with the speed.
