AI Thread Summary
To determine the force needed to move a body from rest to a velocity of 5 m/s over a distance of 15 m in 2 seconds, the mass of the body is essential for calculating the force using the equation F_net = ma. Without knowing the mass, it is impossible to provide a specific force value, as different masses would require different amounts of force to achieve the same acceleration. The discussion highlights the importance of mass in force calculations, using the analogy of pushing a truck versus a small car on a frictionless surface. Therefore, to solve the problem accurately, the mass must be provided. Understanding the relationship between mass, acceleration, and force is crucial in physics problems like this.

Homework Statement


What force is it needed to move a body from rest at velocity of 5m/s on distance 15m, for time of 2s. Assume no friction.

Homework Equations


##F_{net}=ma##

Can I solve this problem without the mass of the body, if yes, what formula is needed? thanks!

If you want an actual number for the force, then you need mass. Think about pushing a truck on ice (zero friction) versus pushing a small car. Wouldn't it require more force for the larger object to attain the same speed?
 

Thread 'Struggling to understand the concept of this 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...

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}...
