A block is released from rest on an inclined plane and moves 3.1 m during the next 2.2 s. The acceleration of gravity is 9.8 m/s 2 . 10 kg µk 37◦ What is the magnitude of the acceleration of the block? Answer in units of m/s 2

Respuesta :

Answer:

[tex]a = 1.28 m/s^2[/tex]

Explanation:

As we know that the block is released on the inclined plane from rest

so here the distance moved by the block is given as

[tex]d = \frac{1}{2} at^2[/tex]

so here we will have

d = 3.1 m

t = 2.2 s

now we will have

[tex]3.1 = \frac{1}{2}a(2.2^2)[/tex]

[tex]a = 1.28 m/s^2[/tex]
