Answer:
8.35 × kg
Explanation:
Remember the formula for heat:
You just need to solve for m, doing so you're left with:
Replace the variables with numbers and that's it.
Impulse on the object: -20 kg m/s
Explanation:
The impulse exerted on an object is a vector quantity equal to the product between the force exerted on the object and the time interval during which the force is applied.
The impulse exerted on an object is also equal to its change in momentum. Mathematically,
where:
m is the mass of the object
u is the initial velocity
v is the final velocity
For the object in this problem, we have
m = 5 kg
u = +6 m/s
v = +2 m/s
Therefore, its impulse is:
The negative sign means the direction of the impulse is opposite to the direction of motion of the object.
