O A car of
mass 200kg
is
25 sec the velocity
what is
Change
moving
with a speed of zombs
increard by tomis,
then
momentum?

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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Who was the first scientist to measure speed as distance over time?

Ascientific blank must be testable and capable of being proven false?
