A powered model rocket is launched in the vertical direction. The altitude of the rocket is 100FT (above ground level) at the end of the powered portion of the flight. The rocket lands 19.676 seconds from the powered portion of the flight.
a) select and label a coordinate system and origin
b)Determine the speed of the rocket at the end of powered flight
c) When during the flight is this speed achieved again?
d)Determine the maximum altitude reached by the rocket
e) Check for the unpowered portion of the flight that t-up + t-down = 19.676 seconds
A sky diver with a mass of 75 kg jumps from an aircraft. The aerodynamic drag force acting on the sky diver is known to be Fd = kV^2, where k = 0.228. Determine the maximum speed of the free fall for the sky diver and the speed reached after 100 m..
After falling from rest from a height of 32 m, a 0.45 kg ball rebounds upward, reaching a height of 22 m. If the contact between ball and ground lasted 1.5 ms, what average force was exerted on the ball?
A 200ft length of steel wire is to carry a tensile load of 340lb. Find the minimum acceptable wire diameter if the maximum allowable stress in the wire is 30ksi, and the lengh of the wire must not increase by more than 2 inches when there is no ch..
