Un pattinatore scende lungo una discesa, percorre poi un tratto orizzontale di 10 m e risale lungo una
salita. Parte da un'altezza di 4,0 m con una velocità
iniziale di 4,2 m/s. Supponi che gli attriti siano tra-
scurabili,
A quale altezza arriva il pattinatore lungo la sa-
lita?
L'altezza a cui arriva dipende dalla lunghezza del
tratto orizzontale di raccordo?

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
