Answer:
The gravitational force is definitely acting downwards towards the ground and this is equal to the weight of the skydiver.
the acceleration a = 7.8 m/s²
Explanation:
Given that :
the mass of the skydiver = 60 kg
Velocity = 50 m/s
Thus; gravitational force is definitely acting downwards towards the ground and this is equal to the weight of the skydiver.
Also; the air resistance is acting upward and the resultant of both forces = mass×acceleration
So;
mg-R = ma
60(9.8) - 120 = 60(a)
588 -120 = 60a
468 = 60a
a = [tex]\frac{468}{60}[/tex]
a = 7.8 m/s²
Hence, the acceleration a = 7.8 m/s²
Answer:
588n
Explanation:
50kg x 9.8m/s2 because that is gravitational pull on earth
