An infant throws 7 g of applesauce at a velocity of 0.5 m/s. all of the applesauce collides with a nearby wall and sticks to it. what is the decrease in kinetic energy of the applesauce?

Δ KE = - 8.75 x 10⁻⁴ J

Explanation:

given,

mass of applesauce = 7 g = 0.007 Kg

initial velocity, u = 0.5 m/s

final velocity, v = 0 m/s

Decrease in kinetic energy = ?

initial kinetic energy

      KE₁ = 8.75 x 10⁻⁴ J

final kinetic energy

      KE₂ =0 J

Decrease in kinetic energy

Δ KE =  KE₂ - KE₁

Δ KE = 0 - 8.75 x 10⁻⁴

Δ KE = - 8.75 x 10⁻⁴ J

decrease in kinetic energy of the applesauce is equal to  8.75 x 10⁻⁴ J

i'm just gonna leave this comment here, so i can get a challange done-
