You are driving at the speed of 33.9 m/s
(75.8484 mph) when suddenly the car in
front of you (previously traveling at the same
speed) brakes and begins to slow down with
the largest deceleration possible without skidding. considering an average human reaction,
you press your brakes 0.595 s later. you also
brake and decelerate as rapidly as possible
without skidding. assume that the coefficient
of static friction is 0.757 between both cars’
wheels and the road.
the acceleration of gravity is 9.8 m/s

.
calculate the acceleration of the car in front
of you when it brakes.
answer in units of m/s

.

Because its not moving at that time hope u understand

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
