Abag is dropped from a hovering helicopter. after 42.4s, calculate the bag’s displacement.

8,809.024m

Explanation:

Displacement , y = (gt^2/2 )

g = 9.8 m/s^2

t = 42.4s

y = (9.8 (42.4*42.4)) / 2

y = 8,809.024m

Net force required to accelerate the car is 6000 N

Explanation:

Here, mass = 3000 kg and acceleration = 2 m/s²

⇒ Force = Mass × Acceleration

              = 3000 × 2 = 6000 N

⇒ F = 6000 N

⇒ M = 3000 kg

⇒ a = 2 m/s²
