Linear Momentum and Second Law of Motion: Practice Problem & Solution

Acceleration of the block is : Linear Momentum and Second Law of Motion diagram: Acceleration of the block is :
1 m/s²
2 m/s²
3 m/s²
4 m/s²

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Linear Momentum and Second Law of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Horizontal component of force is F cosθ = 20√2 cos 45° = 20√2 × 1/√2 = 20 N.

So, Horizontal acceleration =  20N / 10kg  = 2m/s²

2. A frame of reference A is moving rectilinearly and uniformly with a velocity \(\vec{u}\) with respect to an inertial frame B. A body is moving with velocity \(\vec{v}\) and acceleration \(\vec{a}\) in an inertial system B. Assertion (A): When we use Newtons second Law in frame B we write \( \Sigma \vec{F}_{net} = m\vec{a} \). Now when we use the same in frame A we will write exactly same \(\Sigma \vec{F}_{net}\) and \(\vec{a}\) . Reason (R): All inertial system are equally suitable for the description of physical phenomenon.
