ok im doing my physics homework and we have to submit the answers online.

i keep getting these questions wrong and i only have one more try can someone please tell me how to work it?

a 2.5 kg otter starts from rest at the top of a muddy incline 94.6 cm long and slides down to the bottom in 0.50s.

What net external force acts on the otter along the incline? in units of N.

a 3.37 kg book is dropped from a height of 2.0m. The acceleration of gravity is 9.81 m/s^2.

what is its acceleration? in units of m/s^2

what is its weight? in units of N

a 2.70 kg block is in equilibrium on an incline of 23.3°

the acceleration of gravity is 9.81 m/s^2/

what is Fn of the incline on the block?

in units of N

A block with a mass of 5.8 kg is held in equilibrium on a frictionless incline of 27.0° by the horizontal force F

the acceleration of gravity is 9.81 m/s^2

what is the magnitude of F? in units of N

what is the magnitude of the normal force. in units of N

i have made diagrams of them to help me out. i was gonna post them here but its not allowed. maybe im doing the diagrams wrong>

when i try to post it it says:

You are not allowed to post internet addresses

i have scanned my diagrams and then uploaded them so i can post the html, so you can see my work.
