if the 50 kg object slows down to a velocity of 1 m/s how much kinetic energy does it have 100j 50j 25j or none
rodikova [14]

ek =  \frac{1}{2}m {v}^{2}

ek =  \frac{1}{2}(50) {(1)}^{2}

ek =  \frac{1}{2}(50)

ek = 25j

//

I'm not really sure but I do know that it's not 0 because the object is still moving, even if it's only moving at 1 m/s.

A 1.5V battery is connected to a small light bulb with a resistance of 3.5 what is the current in the bulb?
notka56 [123]

Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .

Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the  3.5  has the units of ohms.    Then . . .

  Current = (voltage) / (resistance)  =  (1.5/3.5) = <em>3/7 of an Ampere</em>.

                                                                   (429 mA, rounded)
