Answer:

- 1 m/s ( here (-) means the opposite direction of A)

Explanation:

Let m1=2kg, m2=2kg,u1= 3m/s,u2= -2 m/s, v1= 1m/s

m1u1+m2u2= m1v1+m2v2

2×3+2×(-2) = 2×1 + 2x

2= 2(1+x)

x = -1

Hope it helps

is this true or false? an object with a mass of 9.0kg has an acceleration of 3m/s2. the force acting on it is 3N
ludmilkaskok [199]

The answer is "False". The force acting on the object is 27 N.

According to Newton's second law, when a force <em>F</em> acts on am object of mass <em>m</em>, it produces an acceleration <em>a</em>. The force is given by the expression,

F=ma

Thus, if the body has a mass of 9.0 kg and if it has an acceleration of 3 m/s², then, on substituting the values in the equation for force,

F=ma\\ =(9.0kg)(3m/s^2)\\ =27N

Thus, it can be seen that the force acting on the body is 27 N and not 3 N as is mentioned in the statement. Hence the statement is false.
