Momentum of an object is defined as product of mass and velocity
so it is given as
here it is given that
mass = 0.15 kg
momentum = 6 kg m/s
so by plug in values in the above equation
so its speed will be 40 m/s
<span>Inertia is a property of matter
i hope this help</span>
All except C, feelings are not physical.
Answer:
+9.8m/s^2
Explanation:
The rate of gravity of the object is constant thriughout the surface of the earth.
For falling object, the rate of gravity is positive since the body is coming down (falling)
The rate of gravity is negative if the body is going up
The constant value for acceleration due to gravity is 9.8m.s^2
Since the object is falling, hence the acceleration due to gravity is positive.
Rate of gravity working on the object will be +9.8m/s^2
