another question.
When a horizontal force is applied on a 3kg wooden block, the block moves at a uniform velocity. If the force is increased up to 18N, what is the (new) acceleration of the block? |

kidney is quite easy if u understand the whole process. i have trouble understanding meosis mitosis all that
Added on October 29, 2008, 10:15 pm QUOTE(HotChocolate @ Oct 29 2008, 10:12 PM) Your p is pressure or roll (how you spell that)? i get the same answer as u. but the answer in the book is 4.Pressure = Force/Volume Roll or Density = Mass/Volume Roll and density is the same fyi. F=ma? 18 = 3a a = 6ms-2 the uniform velocity meant there is no resultant force (or friction). Or is it? Not too sure the ques got prob maybe  This post has been edited by pwincess: Oct 29 2008, 10:15 PM |
