Answer:

the answer for your question is option a is the answer for your question OK follow me please mark my answer as brainlest answer

Answer 2

The acceleration of the block is: 10m/s²

Given:

Mass of the block: 10Kg

Horizontal force on the block: 50N

The inclination of the wedge: 37°

To find:

Acceleration of the block

Explanation:

The horizontal component of force = 50Cos37°N = 40N

Vertical component of force = 50sin37°N = 30N

The horizontal component of force due to its weight = mgSin37°N

mgSin37°N = 10 × 10 × 3/5 N = 60N

Total horizontal force = 60N + 40N = 100N

We know,

F = ma

a = F/m

a = 100/10 m/s²

a = 10 m/s²

The acceleration of the block is: 10m/s²
