Ahot-air balloon rises from ground level at a constant velocity of 3.0 m/s. one minute after liftoff, a sandbag is dropped accidentally from the balloon. calculate (a) the time it takes for the sandbag to reach the ground and

0.31 seconds

Explanation:

Initial velocity of bag = -3 m/s = u (upward direction considered as positive)

Final velocity = 0 = v (touches the ground)

a = g = Acceleration due to gravity = 9.81 m/s²

t = Time taken to reach the ground

Equation of motion

∴ Time taken by the bag to reach the ground is 0.31 seconds

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
