Calculate the absolute value of the magnitude of the impact force on a 60 kg parachutist falling at 10 m/s if the time to stop was 0.7 seconds.

85.7 N

Explanation:

According to Newton's second law of motion, F is equivalent to the product of mass and acceleration, ma where m is the mass of parachute in kilograms and a is acceleration.

Acceleration is defined as the rate of change of velocity per unit time hence expressed as

Where v and u represent the final and initial velocities respectively.

Substituting this into initial equation of f then

For this case, the final velocity is zero since it comes ro rest. Substituting 0 m/s dor v and 10 m/s for u then 0.7 s for t we can deduce that

answer

the arrows to the right of earth should point up.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
