The LR5 is the specialist submarine for underwater rescue. The average density of seawater is 1028 kg/ m3.
i. Calculate the increase in pressure as LR5 descends from the surface to a depth of 700m.(g=10m/s2 )

To a of 4 x hz is 1. 0. mm nm nm

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
