I am stuck on how my teacher got to the last equation in #4. Problem Statement: A 2,000 kg rocket carrying 3000 kg of fuel is drifting in space when it...
The formula for U physics acceleration gives the length of time essential for a physique to quit when it is accelerated at a particular velocity. This really is critical for the students of physics since they may have the ability to get to know what may cause objects to accelerate or deceler...
The mistake most people make when engaging in this debate is considering horsepower and torque independently. Almost everyone argues as if they are separate, unrelated values—which they are not. This equation is the second most important thing on this page, and it’s the reason that anyone ...
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. Accelerationa = (v-u) /t Or at = (v-u) Ort = (v-u) /a Next step is to substitute the equation for the time t into the second equation of motion s=ut +...

force must be applied at a right angle to its path. The radius (r) of this circle is equal to the mass (m) times the square of the velocity (v) divided by the centripetal force (F), or r = mv^2/F. The force can be calculated by simply rearranging the equation: F= mv^2/r...
What is the equation for displacement as a function of time? An object is launched at a velocity of 20 m/s in a direction making an angle of 25 degrees upward with the horizontal. What is the magnitude of the velocity of the object just before it hits the ground?
In this problem the ball traveled 50 m starting from rest in 10 s. We need to calculate acceleration. This can be calculated very easily using the equation $$\boxed{s=ut+\dfrac12ft^2} $$ where {eq}f {/eq} is the acceleration , {eq}u {/eq} is ...
The density of mercury is {eq}\rm 13600 \ kg/m^3 {/eq} at 0 degree Celsius. What would be its density at 20 degree Celsius? {eq}\rm (\beta = 0.95 \times 10^{-3} (^{\circ}C)^{-1}) {/eq} Volume expansion We ...
What Is Market Momentum? Momentum is the rate of acceleration of asecurity'sprice—that is, the speed at which the price is changing. Market momentum refers to the aggregate rate of acceleration for the broader market as a whole. Market momentum can be used as a measure of overallmarket se...
