A 55-kg pilot flies a jet trainer in a half vertical loop of 1200 m radius so that the speed of the trainer decreases at a constant rate. The plane has a speed of 550 km/hour at point A and the pilot experiences weightlessness at point C (the normal force from the seat bottom is zero). Determine a) The deceleration of the plane b) The force exerted on her by the seat of the trainer when the trainer is at point B

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?
