Two identical bowling balls are rolling on a horizontal floor without slipping. the initial speed of both balls is v = 10 m/s. ball a encounters a frictionless ramp, reaching a maximum vertical height ha above the floor. ball b on the other hand rolls up a regular ramp (i. e. without slipping), reaching a maximum vertical height hb above the floor. which ball goes higher and by how much? show the steps of your calculations.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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.
