Acar starts from rest and travels 5.0 s with a uniform acceleration of 1.5 m/s2. the driver then applies the brakes, causing the car to slow down at a rate of 2.0 m/s2. if the brakes are applied for 3.0 seconds, how fast is the car going at the end of the braking period and how far has it gone from the start?

The human body stores chemical energy from digested food. some of the chemical energy is converted into mechanical energy when the body moves. which statement best supported by this information

What are the three ways that an object can accelerate

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
