A 1.50 m-long, 480 g rope pulls a 8.00 kg block of ice across a horizontal, frictionless surface. The block accelerates at 2.40 m/s^2. How much force pulls forward on (a) the ice, (b) the rope?

2. Relevant equations

F=m*a

3. The attempt at a solution

for A i got the right answer by

Acceleration of the block = 2.4 m/s^2

mass of the block = 8kg

Force = 8*2.4 = 19.2 N

but for b i did:

Acceleration of the rope = Acceleration of the block = 2.4 m/s^2

mass of the rope = 0.480kg

Force = 0.480*2.4 = 1.152 N

and it was wrong. anyone know where i messed up?
