A parcel is connected to a flying drone as illustrated above. Note that the coordinate system is given
with +y pointed in the upwards direction. Holding the parcel, the drone takes off moving straight up
with a velocity of 8.40. m/s. Note that, as usual, y = 0 at the ground.
After 8.00 s, the drone accidentally releases the parcel! The parcel is in "freefall" immediately after it is
released, as defined in Lecture 7. Assume that the magnitude of the acceleration, g = 9.81 m/s?, and that
the drone continues with the same velocity after releasing the parcel. Ignore the effects of air-resistance.

c) What is the acceleration of the parcel immediately after it is released? (Remember acceleration
is a vector and the sign is important (i.e. "+" for pointing up, or "-" for pointing down.

Expert Solution

An aircraft equipped with a LiDAR sensor captures a terrestrial topography. The LiDAR system emits pulses with pulse repetition frequency (PRF) of 160 kHz, and the aircraft is hovering at the altitude of 750 m with a speed of 180 mph. The beam of lidar pulses is steered along a line perpendicular to the direction the fight, or swath width, with steering frequency of 80 Hz. a) To avoid the ambiguity of the pulses emitted next to each other, what’s the limitation of swath width of the LiDAR system? b) Estimate the along-track resolution and the resolution across the swath width, assuming each pulse corresponds to each grid of the topography

A small trailer and its load have a total mass of 250 kg. The trailer is supported by two springs, each of constant 10 kN/m, and is pulled over a road, the surface of which can be approximated by a sine curve with an amplitude of 40 mm and a wavelength of 5 m (i.e., the distance between successive crests is 5 m and the vertical distance from crest to trough is 80 mm). Determine (a ) the speed at which resonance will occur, () the amplitude of the vibration of the trailer at a speed of 50 km/h.
