As we know that Force = mass * acceleration.   
Here a force of 186 N acting on 7.3 kg ball will create acceleration = 186/7.3 = 25.48 m/s2  
Also, change in velocity can be found as, acceleration multiplied by time it is acting on object. 
Therefore, change in velocity = 24.48 * 0.4 = 10.19 m/s

Given are: Force = 186 N; Mass = 7.3 Kg; time = 0.40 s Initial Velocity Vi = 0
Final Velocity Vf = ?
Unknown: Change in velocity or acceleration 
F =ma;  but a = Vf - Vi/t  Solve for Vf or Final velocity
therefor  F = m(Vf-Vi/t) Ft = m(Vf - Vi/t)   But Vi = 0
Vf = (186 N)(0.40 S)/7.3 Kg  answer Vf = 10.2 m/s
Solving for acceleration or change in velocity
a = Vf - Vi/t
a = 10.2 m/s - 0/0.4s  therefore change in velocity a = 25.5 m/s²

A tank of volume 0.25 ft is designed to contain 50 standard cubic feet of air. The temperature is 80° F.Calculate the pressure i
slavikrds [6]

Answer:

The inside Pressure of the tank is 4499.12 lb/ft^{2}

Solution:

As per the question:

Volume of tank, V = 0.25 ft^{3}

The capacity of tank, V' = 50ft^{3}

Temperature, T' = 80^{\circ}F = 299.8 K

Temperature, T = 59^{\circ}F = 288.2 K

Now, from the eqn:

PV = nRT                      (1)

Volume of the gas in the container is constant.

V = V'

Similarly,

P'V' = n'RT'                       (2)

Also,

The amount of gas is double of the first case in the cylinder then:

n' = 2n

\]frac{n'}{n} = 2

where

n and n' are the no. of moles

Now, from eqn (1) and (2):

\frac{PV}{P'V'} = \frac{nRT}{n'RT'}

P' = 2P\frac{T'}{T} = 2\times 2116\times \frac{299.8}{288.2} = 4499.12 lb/ft^{2}

gladu [14]
<span>9.50x10^2 newtons A pascal is defined as 1 newton per square meter. So let's multiply the pressure by the surface area of the box lid. F = 1.00x10^-2 m^2 * 9.50x10^4 N/m^2 = 9.50x10^2 N So it will take 9.50x10^2 newtons of force to remove the lid from the box.</span>
