a spacecraft covers the last straight stretch of an inter-galactic space race in 2.5 days. During that time, it uses its hyper-drive and speeds up from 65,640 km / h to 120,600 km / h. What acceleration does the hyperdrive allow for?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

Ascientific blank must be testable and capable of being proven false?
