If a 70-kg swimmer pushes off a pool wall with a force of 250 N what is her acceleration
jek_recluse [69]
F= MA 
force equals mass time acceleration 
250 N = (70 kg ) (A)
250/70 = 3.5 which is about 4 m/s 
Hope this helps

Two blocks of masses m1 and m2 are connected to each other on an Atwood machine (the blocks are connected by a string going over
ddd [48]

Answer:211.11 gm

Explanation:

Given

mass of lighter block m_1=100 gm

mass of heavier  block is m_2

acceleration of system a=3.5 m/s^2

From diagram

for lighter block

T-m_1g=m_1a

T=m_1(g+a)

For heavier Block

m_2g-T=m_2a

T=m_2(g-a)

Equating Tension T

m_1(g+a)=m_2(g-a)

m_2=m_1\cdot \frac{g+a}{g-a}

m_2=m_1\cdot \frac{9.8+3.5}{9.8-3.5}

m_2=0.1\cdot 2.11

m_2=0.2111 kg

m_2=211.11 gm
