If the blocks are released from rest, which way does the 10 kg block slide, and what is its acceleration? enter a positive value if 10 kg block accelerates up the rump, and a negative value otherwise.

Suppose that θ=35∘

First, you need to set up equations for both blocks.

Let m1 be 10kg and m2 be 5kg and for our computations suppose right is positive and up is positive

For m1 the solution is:
Sigma Fx = ma 
T - m1gsin35 = m1a where T = tension 

For m2 
m2g - T = m2a 

Add the two equations together 

m1a + m2a = T-m1gsin35 + m2g - T 
a(m1 + m2) = m2g - m1gsin35 
a= (5*9.8 - 10*9.8*sin35)/(10 + 5) 
a= -0.48m/s/s 

it would be kevlar ^^

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
