Homework Statement During a serve, a tennis racket of mass 1.4 kg is given an angular acceleration of 163 rad/sec2. At the top of the serve, the racket has an angular speed of 16 rad/sec. If the distance between the top of the racket and the shoulder is 1.5 m, what is the total acceleration of...

A shell of mass 0.4 kg is at rest in a gravity-free environment when it suddenly explodes into three fragments. The mass and x,y components of two of the fragments is given in the table:particle mass (kg) vx (m/s) vy (m/s) [1] 0.12 25 58 [2]...

part a is correct because the homework is on a software and it accepted my answer

1. Homework Statement Blocks of mass 5, 10, and 25 kg are lined up from left to right in that order on a frictionless surface so each block is touching the next one. A rightward-pointing force of magnitude 14 N is applied to the left-most block. a) What is the magnitude of the force that...

lol i still don't know what numbers to use in what formula

so then i do 14=5a then the a is 2.8 n if i multiply that I am going to get 14 again ... I am confused !:confused:

so then what formula do i use ?

F = (5)(.35) = .175

sorryy my mistake i got it for part a which was 8.75 but when i did it again for part b it said wrong

i tried f = ma this is what i did m = 5+10+25 = 40 14 = 40(a) a = .35 but it said that's not the right answer
