A0.75 kg teddy bear is nudged off a window sill and falls 2.05 m to the ground. what is its kinetic energy at the instant it hits the ground?

V=6,342 m/s

Explanation:

In order to calculate the kinetick energy you need to multiply the speed by the mass of the object, to calculate the final velocity or t the point of impact you use the next formula:

So the final velocity when the tedy bear hits the ground is 6,342 m/s.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
