The weight of the buggy was 40n on mars. when the buggy landed on mars it rested on an area of 0.025m squared. calculate the pressure exerted by the buggy on the surface of mars. give the unit

its c its is a mixture of gases

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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.
