A 4.0 kg mass has a velocity of 10 m/s to the EAST. The 4.0 kg mass is subjected to a constant net force of 16 N to the WEST for

3.0 sec. What is the velocity of the 4.0 kg mass at the end of the 3.0 sec interval?​

Answer:

v = 2.0 m/s West

Explanation:

Let East be the positive direction

The initial momentum of the mass is p = mv = 4.0(10) = 40 kg•m/s East

This is acted on by an impulse of p = Ft = 16(3.0) = 48 N•s west

An impulse will result in a change of momentum

so final momentum of the mass is

40 - 48 = -8 kg•m/s or 8 kg•m/s West

-8 = 4.0v

v = -2.0 m/s or 2.0 m/s West

You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 degre
katen-ka-za [31]
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T], 
Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have 
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6 
Therefore, V = 352.6 m/s.

What is the dimensional formula of pressure ??​
Igoryamba

Answer:

pressure is equal to the net amount of force acting per unit area. Dimensional Formulae of force is M1L1T-2 and of area is L2. Therefore Pressure's dimension can be obtained by calculating Force by Area. Dimensional formula of pressure difference is M1L-1T-2.
