At=v-u, where u=0
t= v/a=42/6 = 7
Answer: 7 seconds
Answer:
Explanation:
Positive values for position indicate that the object is in front of the starting point and negative values tell us that the object is behind the starting point. (time = 9.5, position = 0) the object is at the starting point.
Answer:
Explanation:
Given
Potential Energy of a particle is given by 
For minimum or maximum Potential Energy differentiate U(x) w.r.t x
putting 
To know minimum value check 
at x=-2
so at x=-2 potential energy is minimum 
Answer:
Option A is the correct answer.
Explanation:
The instantaneous acceleration = Change in velocity in velocity/Time taken
The slope of the graph should give instantaneous acceleration.
Slope of a graph = Change in value of Y -axis / Change in values of X -axis
Comparing both the equations
Change in value of Y -axis = Change in velocity in velocity
Change in values of X -axis = Time taken
So velocity values should be on the Y axis and Time values should be on the X axis.
Option A is the correct answer.
