Una grúa sube en forma vertical un bloque hasta una altura de 4 m, a velocidad constante y en un tiempo de 10 s. La potencia disipada para realizar ese trabajo es de 2000 W. ¿Cuál es el peso del bloque? En esta situación peso=fuerza ya que el desplazamiento es vertical?

5000N

Explanation:

Power = Workdone/Time

Power = force × distance/time

Given

Power = 2000W

Distance (height) = 4m

Time = 10secs

Substitute into the formula to get the weight(force)

2000 = force × 4/10

2000 = 4F/10

Cross multiply

2000×10 = 4F

20,000 = 4F

Divide both sides by 4

4F/4 = 20,000/4

F = 5000N

Hence the weight of the block is 5000N

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
