Three astronauts, propelled by jet backpacks, push and guide a 120 kg asteroid toward a processing dock, exerting the forces shown in Fig. 5-37, with `F_(1)=32N,F_(2)=55N,F_(3)=41N, theta_(1)=30^(@)`, and `theta_(3)=60^(@)`. What is the asteroid's acceleration (a) in unit-vector notation and as (b) a magnitude and (c) a direction relation relative to the positive direction of the x axis ?

In the overhead view of Fig. 4-40, Jeeps P and B race along straight lines, across flat terrain, and past stationary border guard A. Relative to the guard, B travels at a constant speed of 25.0 m/s, at the angle theta_(2)=30.0^(@) . Relative to the guard, P has accelerated from rest at a constant rate of 0.400m//s^(2) at the angle theta_(1)=60.0^(@) . At a certain time during the acceleration, P has a speed of 40.0 m/s. At that time, what are the (a) magnitude and (b) direction of the velocity of P relative to B and the ( c) magnitude and (d) direction of the acceleration of P relative to B?
