trieve the ball, you apply your brakes for 1.20 s. the car slows down from 15.0 m/s to 9.00 m/s. the mass of the car is 1290 kg. (b) how far did the car move while braking?

Since the acceleration of car is uniform so the distance traveled by car while brakes are applied is given by

d = \frac{v_f + v_i}{2}*t

given that

v_f = 9 m/s

v_i = 15 m/s

t = 1.20 s

now plug in all data in above formula

d = \frac{15 + 9}{2} * 1.2

d = 14.4 m

so car will cover 14.4 m distance while it apply brakes

The atmosphere of Mercury and Mars are very thin. What effect does the thin atmosphere have on the temperature on the surface of
KengaRu [80]

Answer:

Very hot during the day and very cold at night.

Explanation:

Due to the thin atmosphere, they have very hot climate during the day time and very cold climate at night. This happens because they contain very low amounts of greenhouse gases. These gases retain the heat at night. The atmosphere also prevents excessive light and UV rays from entering. The thin  atmosphere leads to many asteroids and comets hitting the surface of the planet. On earth, these asteroids usually, burn up in the mesosphere layer of the atmosphere. These asteroid collisions cause massive fires. This in turn,  causes the temperature to increase during the day. During the night time, massive fires cannot burn due to the low temperature because of the lack of greenhouse gases.

inn [45]
It depends how large the object is. But, if it is 2 by 4, most likely the wood sieges more than the glass. Hope this helps.
