An 80 kg person is parachuting and is experiencing a downward acceleration of 2.8 ms-2. The mass of the parachute is 5 kg. The upward force on the open parachute is (take, g = 9.8 ms-2)

1) 595 N

2) 675 N

3) 456 N

4) 925 N

Answer: 1) 595 N

Solution:

m = (80 kg + 5 Kg) = 85 kg

mg – F = ma

85 x 9.8 – F = 85 x 2.8

F = 85 x 9.8 – 85 x 2.8

= 85 (9.8 -2.8)

= 85 x 7

= 595 N
