Ablock slides across a frictionless horizontal surface with constant acceleration 4.15 m/s2 and over a time interval reaches a final velocity of 12.2 m/s.
(a) if its initial velocity is 6.10 m/s, what is its displacement (in m) during the time interval? (indicate the direction with the sign of your answer.) m
(b) what is the distance it travels (in m) during this interval? m
(c) if its initial velocity is −6.10 m/s, what is its displacement (in m) during the time interval? (indicate the direction with the sign of your answer.) m
(d) what is the total distance it travels (in m) during the interval in part (c)?

momentum of soft ball three times less than baskey ball

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.
