nalin [4]

Answer:

The initial velocity of the cart was 0.91m/s.

Explanation:

When the car comes to a stop it has delivered all of its kinetic energy to the spring; therefore,

$\dfrac{1}{2}kx^2 = \dfrac{1}{2} mv^2$

solving for $v$ we get:

$v = x\sqrt{\dfrac{k}{m} },\\$

we put in $k = 4.21*10^{5}N/m$ , $m = 5.18*10^{4}kg$ , and $x = 0.32m$ to get:

$v = (0.32m)\sqrt{\dfrac{4.21*10^5}{5.18*10^4} },\\$

$\boxed{v = 0.91m/s.}$
