A 2kg object experiences two concurrent forces, f1=100N at 37 degrees above the positive x-axis and f2=80N at 53 degrees above the x-axis (sin37 and cos53=0.6, sin53 and cos37=0.8). Find 1. The component in the x-axis
2. Component in the y-axis
3. Resultant force
4. The direction of the resultant force
5. The acceleration of the body

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

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.
