At full power, how long would it take for the car to accelerate from 0 to 58.0 mph ? neglect friction and air resistance.

For the given problem, we calculate the required time by using the formula P = W/t. 

P = [(1/2)mv_f^2 – (1/2)mv_i^2]/ t 

The car accelerates from 0 -58 mph, so the power engine will be 

P = (1/2) x m x 58^2 / t = 1682 m / t 

According to the problem, the engine produces full power so the time required can be calculated as  

420.5 m / 1.40 = 1682 m / t 

t = 5.6 seconds

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
