A50 kg wooden crate is slid across a flat surface for 60 meters by a force of 90.0 n. if the coefficient of sliding friction is 9.15, what will be the final speed of the crate?

the answer is 46 mls because when you add the speed per second it increses the speed

the answer is b i think

it would be kevlar ^^

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.
