Here is the problem that I am having a horrible time with:

Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration less than 800 m/s2 lasting for any length of time will not cause injury, whereas an acceleration greater than 1000 m/s2 lasting for at least 1 ms will cause injury. Suppose a small child rolls off a bed that is 0.40 m above the floor. If the floor is hardwood, the child's head is brought to rest in approximately 2.0 mm. If the floor is carpeted, this stopping distance is increased to about 1.2 cm. Calculate the magnitude and duration of the deceleration in both cases, to determine the risk of injury. Assume that 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.

Hardwood floor magnitude _______ m/s2
Duration _____ ms

Carpeted floor magnitude _______ m/s2
Duration _____ ms

A record of travel along a straight path is as follows:

1. Start from rest with constant acceleration of 2.16 m/s2 for 15.0 s.
2. Maintain a constant velocity for the next 1.45 min.
3. Apply a constant negative acceleration of -8.74 m/s2 for 3.71 s.

What was the total displacement for the trip (in meters)?

What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip (in m/s)?

Please help if you know anything about Physics!
