Question

Two blocks of masses 1.0 kg and 2.0 kg, respectively, are pushed by a constant applied force F across a horizontal frictionless table with constant acceleration such that the blocks remain in contact with each other, as shown above. The 1.0 kg block pushes the 2.0 kg block with a force of 2.0 N. The acceleration of the two blocks is

0

1.0 m/s2

1.5 m/s2

2.0 m/s2

3.0 m/s2

Answer 1

Answer:

1.0 m/s^2

Explanation: happy to help :)

Answer 2

Answer: $1\ m/s^2$

Explanation:

Given

Masses of the block are $m_1=1\ kg$  and

$m_2=2\ kg$

Force applied by $1\ kg$ block on $2\ kg$ block is $2\ N$

From the free body diagram of $2\ kg$ block, the net force on

$\therefore m_2a=2\\\\\Rightarrow 2\times a=2\\\\\Rightarrow a=\dfrac{2}{2}\\\\\Rightarrow a=1\ m/s^2$

Thus, the acceleration of two blocks is $1\ m/s^2$
