Just after opening a parachute of negligible mass, a parachutist of mass 85.5 kg experiences an instantaneous upward acceleration of 1.12 m/s2. Find the force of the air on the parachute.
To find the force of the air on the parachute, we can use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration. In this case, the mass is the mass of the parachutist.
The formula for force is:
Force = mass × acceleration
Given information:
Mass of the parachutist (m) = 85.5 kg
Acceleration (a) = 1.12 m/s²
Substituting the values into the formula, we get:
Force = 85.5 kg × 1.12 m/s²
Calculating the value, we find:
Force = 95.76 N
Therefore, the force of the air on the parachute is 95.76 Newtons.
