A 0.30 kg ball of putty is thrown at a stationary 1.2 kg cart. The ball of putty is initially moving with a speed of 6.0 m/s. Th
Lemur [1.5K]
<span>In order to determine the speed of the entire assembly, we employ conservation of momentum. Momentum p = mv where m is the object's mass and v is the velocity.
   The putty ball's initial momentum p1 = 0.3kg*6m/s = 1.8 kg*m/s
   That momentum is conserved, so the momentum of the new system having mass 0.3 kg + 1.2 kg = 1.5 kg is:
   1.8 kg*m/s = 1.5kg*v. Solving for v, we find that the velocity is 1.2 meters/second.</span>

The driver of a 770 kg car decides to double the speed from 23.1 m/s to 46.2 m/s. What effect would this have on the amount of w
Ne4ueva [31]

Answer:

The final kinetic energy is four times of initial kinetic energy when speed of the car doubles.

K_{2} = 4 K_{1}

Explanation:

Mass of the car = 770 kg

initial speed V_{1} = 23.1 \frac{m}{s}

Final speed V_{2} = 46.2 \frac{m}{s}

Initial kinetic energy K_{1} = \frac{1}{2} m V_{1} ^{2}

⇒ K_{1} = 0.5 × 770 × 23.1^{2}

⇒ K_{1} = 205440 J

Final kinetic energy  K_{2} = \frac{1}{2} m V_{2} ^{2}

⇒ K_{2} = 0.5× 770 × 46.2^{2}

⇒ K_{2} = 821760 J

Thus K_{2} = 4 K_{1}

Therefore the final kinetic energy is four times of initial kinetic energy when speed of the car doubles.
