The different molecules that make up the air in a room have, on average the same kinetic energy. How does the speed of the diffe

prisoha [69]

Answer:

speed of molecule ∝ 1/mass of molecule.

Explanation:

The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.

Therefore , it can be written as

speed of molecule ∝ 1/mass of molecule.

During 9.97 seconds a motorcyclist changes his velocity from v1,x = -36.5 m/s and v1,y = 10.9 m/s to v2,x =-21.9 m/s and v2,y =

svetoff [14.1K]

Average acceleration is defined as

$a = \frac{v_f - v_i}{t}$

here

$v_f = final\: speed$

$v_i = initial\: speed$

$t = time$

now for x direction we can say

$a_x = \frac{v_{2x} - v_{1x}}{t}$

$a_x = \frac{-21.9 + 36.5}{9.97}$

$a_x = 1.46 m/s^2$

Similarly for Y direction

$a_y = \frac{v_{2y} - v_{1y}}{t}$

$a_y = \frac{27.5 - 10.9}{9.97}$

$a_y = 1.66 m/s^2$

so above is the acceleration in x and y directions
