You push a box across the floor with a force of 30n you it 15 meters in 8 seconds. how much work did you do how much power did you see

Answer : W = 450 J and P =  56.25 Watts

Explanation :

It is given that,

Force, F = 30 N

Distance, d = 15 m

Time, t = 8 sec

The work done is given as :

W = F.d

So, the work done to push a box across the floor is 450 N.

Mechanical power is defined as,

P = 56.25 Watt

The power is 56.25 Watts.

Hence, this is the required solution.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
