hi,(adsbygoogle = window.adsbygoogle || []).push({});

i need some help w/ this problem:

a) A block of mass 2.00 kg is pushed 2.32 m along a frictionless horizontal table by a constant 17.7 N force directed 25.5 degbelow the horizontal. Determine the work done by the applied force.

b) Determine the magnitude of the normal force exerted by the table.

For part a i used the formula W= Fcos(theta) delta X and i keep coming up with the answer 37.1 joules. It's not right though, and i don't know what i'm doing wrong. help please. thanks. lilly
