Pravat exerts a force of 30 n to lift a bag of groceries 0.5 m. how much work did pravat do on the bag?

0 j

15 j

30 j

60 j

The answer is 15 J. The work (W) is the product of the force (F) and the distance (d): W = F * d. We know that: F = 30 N and d = 0.5 m. Now, let's substitute this in the formula for the work. W = F * d. W = 30 N * 0.5 m = 15 N * m = 15 Joules = 15 J.

The answer is 15j i took the test you guys!

la masa de un cuerpo = 67.308 kg

Explanation:

De la pregunta, sabemos que,

magnitud de fuerza (F) = 350 N = 350 Kg / m /

Aceleración (a)= 520 cm  / = 5.20 m /

A encontrar: la masa de un cuerpo (m)

Nosotras sabemos que, F = m *a

m =

   =

   = 67.308 kg

Entonces, la masa de un cuerpo = 67.308 kg
