Suppose that a box is accelerating at a rate of 2 m/s2 If the net force is tripled and the mass is doubled, then what is the new acceleration of the box?
The correct option is (B) 3 m/s2
According to the question
Let F be the force acting on the body with mass M.
given acceleration a = 2 m/s2
From the Newton's second law we know
Now, the force is triple and mass is doubled.
So we can write
a1 be the new acceleration
From (1) the value of FM=2
So, a1=32×2=3 m/s2
Hence the new acceleration is 3 m/s2
