Climbing a 10m Ladder: Calculating the Work for a 50kg Student

[almost__overnow]

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?
