GeneCards Summary for HNRNPU Gene. HNRNPU (Heterogeneous Nuclear Ribonucleoprotein U) is a Protein Coding gene. Among its related pathways are mRNA Splicing - Major Pathway and Gene Expression. GO annotations related to this gene include poly(A) RNA binding and kinase activity. An important paralog of this gene is HNRNPUL1.
1 What force is needed to accelerate a 1,000 kg car from 72 to 108 km/hr over a time period of 5 s? Answer.  An unbalanced force of 18 N is needed to give an object an acceleration of 3 m/s2. What force is needed to give this very same object an acceleration of 10 m/s2?
All of these will contribute to the force involved in the initial impact, but speed really is king. Force increases proportionally as the weight of the vehicle increases, but speed has an exponential influence on collision forces. Several things can give us clues about how fast the car was traveling at impact.
