Assume a small child rolls off a bed that is 0.38m above, Ask an Expert

Academics

Q. Assume a small child rolls off a bed that is 0.38m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.2mm. If the floor is carpeted, this stopping distance is increased to about 1.1cm. computed the magnitude and duration of the deceleration in both cases, to determine the risk of injury. Suppose the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate.
