(im on a study guide for (honors) physics and i have a test tomorrow. need on these questions)
1. a teenager pushes a 15 kg walmart cart with a force of 33 n to moves it down the aisle at a constant velocity. what is the coefficient of friction?
2. the coefficient of friction between a sled and some snow is .2 on a cold day. if a student can pull the 10 kg sled using a force of 15 n. what is the coefficient of friction?

this could be newton#'s law of cooling. the cooling curve is exponential

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

its a 5.5 n

glad that

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.
