A small mailbag is released from a helicopter that is descending steadily at 1.69 m/s.

(a) After 3.00 s, what is the speed of the mailbag?

v = m/s

(b) How far is it below the helicopter?

d = m

v = m/s

d = m

A container with mass m kg is dropped by a helicopter from height h km at...

A container with mass m kg is dropped by a helicopter from height h km at time t=0, with zero velocity. from the outset, its fall is controlled by gravity and the force of air resitance, f(v)= -kv, where v is the current velocity of the container. in t seconds after the drop, a parachute opens, resulting in an increase of air resistance up to f(v) = -kv. determine the time t at which the container touches the ground. and...

RotateUP Co. is a small company that offers helicopter rides from Bellevue, Kirkland and Bothell to downtown Seattle. Due to state regulations, two able helicopter pilots must be in any commercial helicopter. Each ride takes half an hour. The company’s cost come from paying the helicopter pilots ($75 per hour) and the helicopters themselves (rental cost is $100 per hour). A) If you were to draw the isoquants for this company, would they be L-shaped, straight lines or curved lines?...
