Question

A skydiver with a mass of 70 kg accelerates to Earth at a rate of 9.8 m/s2 due to gravity. What is the force on the skydiver? Explain how you determined the answer and its units.

Answer 1

Step-by-step explanation:

GIVEN DATA

Mass=70kg

Acceleration =9.8m/s2

RTF=Force

since P(momentum)=Mass×Velocity

SOLUTION

FROM NEWTONS SECOND LAW OF MOTION ,

F = △P(change in momentum)

t(time)

F = P2 -P1

t

F= Mv2-Mv1

t

F=M( v2-v1) ,(a=v2-v1)

t t

1. F= m×a

F= 70 × 9.8

F= 686 N

ANSWER EXPLANATION IN WORDS

That question is related to Newton's second law of motion, the question ask you to find the force it gives you a mass and a acceleration As we know that the SI unit of acceleration is newton per kilogram or metre per second square It is correct to write metre per second square instead of Newton Per kilogram because because all of them are the SI unit of acceleration so that is the answer we get 686 Newton by Force .
