AI Thread Summary
To calculate the work required for a 50 kg student to climb a 10-meter ladder, the weight of the student must first be determined using the formula weight = mass x gravity. The gravitational force is approximately 9.8 m/s², so the student's weight is 50 kg x 9.8 m/s², equaling 490 Newtons. Work is calculated by multiplying force (in Newtons) by distance (in meters), thus work = weight x height. Therefore, the work done in climbing the ladder is 490 N x 10 m, resulting in 4900 Joules. This calculation illustrates the relationship between mass, gravity, and the work done against gravitational force.

How much work is required for a 50 kg student to climb a 10 meter ladder?

i know that work = f x d but it doesn't tell the Newton so what do i multiply with 10 m?

The force of gravity acting on an object is its weight. Weight=mg. If you multiply the 50 kg student's mass by 9.8m/s^2 (g is the acceleration of gravity equal to 9.8m/s^2 on earth), you get the student's weight in Newtons (1 kg(m)/s^2 = 1 Newton). So how much work is required?
 

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}...
