Projectile Mass Calculation: 275m/s vs 145g at 325m/s

AI Thread Summary
To find the mass of a projectile fired at 275 m/s that has the same momentum as a 145g projectile fired at 325 m/s, one must first understand the definition of momentum, which is calculated using the formula p = mv. The momentum of the 145g projectile can be calculated by converting its mass to kilograms and multiplying by its velocity. Since the two momenta are equal, the mass of the 275 m/s projectile can be determined by setting the two momentum equations equal to each other and solving for mass. This involves basic algebraic manipulation to isolate the mass variable. The discussion emphasizes the importance of understanding momentum for solving the problem effectively.

find the mass of a projectile when fired at 275m/s if it is to have the same momentum as a 145g projectile fired at 325m/s
 
Physics news on Phys.org
What is the definition of momentum?
 
i don't know it doesn't say any where
 
You must not have looked very many places.

Momentum is defined as

p = mv

where p is momentum, m is mass, and v is velocity.

if anyone can help I've been working on this for an hour
 
How can we find the momentum of the 145g object? How could we find the momentum of the 275 m/s object? These two momentums are equal, so what do we do with things that are equal?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
