Question

Find acceleration of a body of mass 10kg when it is subjected to a horizontal line of 100N, if it is moving along (I) a straight horizontal line, (ii) a horizontal surface which produces a frictional force of 80N.​

Answer 1

Answer:

Step-by-explanation:

Force(F) =100 N

Friction force = 80 N

So, net force acting on the block in horizontal direction = 100N - 80N = 20N

Acceleration of the body = Net force / mass

= 20N/10kg

= 2 m/s²
