Question

Force is applied on an object of mass 2 kg at rest on a frictionless horizontal surface as shown in the graph is speed of object at t=1

Answer 1

Answer:

Explanation:

Here, Force is applied on an object of mass 2 kg at rest on a frictionless horizontal surface.

by spliting the force co-ordinate , we obtain acceleration time graph with peak acceleration at t = 0 sec which is 10m/s².  

Thus, acceleration remains constant till t is 5 sec,

Therefore, the velocity for 1 sec = at = 10m/s.

Answer 2

‼️I SAW THE ABOVE ANSWER FOR THIS QUESTION WHO EVER WRITES PLEASE KNOW THAT THIS QUESTION HAVE TWO ANSWERS:

1. WHEN THE LARGER BLOCK IS KEPT FIRST TO THE HORIZONTAL THEN THE ANSWER IS 10m/s^2

2. BUT IF THE SMALLER BLOCK IS KEPT FIRST TO THE HORIZONTAL THEN THE ANSWER IS 7.5m/s^2
