A skier is standing still on a flat area of snow. The weight of the skier is 550 N. The total area of his skis in contact with the ground is 0.015
m2.
What is the pressure exerted on the ground by the skier?

3700 N / m2
37 000 N/m2
8.3 N/m2
0.83 N/m2

We know

Most nearest value is 37000N/m^2

Hence option b is correct

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.
