Version 3 1) Ballis at the top of a building Ball 2 is at the bottom of the building of height H. Ball 2 is
thrown up with a speed of 2V and Bal 1 is thrown down at a speed of 3V. Use the bottom to be
your reference level
Al Find an expression for the time at which they meet in terms of H and V,
B) Find the velocity at which they pass each other in terms of Vugh.
Find the height above the ground they meet in terms of Vg, h.
D) Plot graphs of attacceleration vs timel, -tſvelocity vs time), and x-t{position vs time), show
they intercept of the at graph and the x-t graph, show the y intercept and the slope of the
position is time graph atte.

Explanation: idk

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
