Given a sphere with radius r, find the height of a pyramid of minimum volume whose base is a square and whose base and triangula
r faces are all tangent to the sphere. What if the base of the pyramid is a regular n-gon? (A regular n-gon is a polygon with n equal sides and angles.) (Use the fact that the volume of a pyramid is V = 1 3Ah, where A is the area of the base.)

As it is given here
initial speed is
After 4 seconds the final speed is
so here we can use the formula of acceleration using kinematics
so here it will accelerate at 2 m/s^2 rate.

As it is given here
initial it starts from rest
After 2.5 seconds the final speed is
so here we can use the formula of acceleration using kinematics
so here it will accelerate at 6 m/s^2 rate.

i think question is not correct as in first line it is saying about a bag of trash and then in next line it is asking for the position of Jumper and bridge.
