1) A box of mass 42kg sits on the top of a ladder. Neglecting the weight of the ladder, find the tension in the rope. Assume the rope exerts horizontal forces on the ladder at each end.
m1g – T = m1a
The Attempt at a Solution
T = m1g - m1a
This is the formula i know for calculating the tension
I have mass has 42 kg. But what is the value for acceleration here? Also I don't know because i have values for h and θ in the diagram.
