CAN YOU GUYS PLEASE HELP I AM STRUGGLING According to Newton's second law, if you have an object that is put under acceleration due to a force, how could you reduce the acceleration on the object by half if you keep the force the same? a Reduce the mass to zero b Increase the force c Double the mass d You cannot decrease the acceleration with the same force

Astate of matter all that has define volume and can flow is a(n)

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.
