Aspacecraft is in orbit around mars. suppose that it was previously observed to have speed 5 km/sec while at a distance r = 5000 km from planet center. suppose it is now at a distance r = 6000 km from planet center. what speed would you expect it to be traveling at now? note that for mars we have gmmars = µmars ' 42, 828 km3 /sec2

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped
