Acceleration Problems II

Physical Science and Technology

 

1.         A gigantic rat is running along the street with an initial velocity of 7.2 m/s.  If it accelerates at a rate of 4.2 m/s2 for 11.5 s, what will its final velocity be?  Use the Five Steps.

 

2.         A skinny turkey is plummeting from the top of Mary’s Peak.  When it lands, its final velocity is 752.1 m/s.  If it fell for 31.5 seconds, and it accelerated at 9.8 m/s2, what was its initial velocity?  Use the Five Steps.

 

3.         A small stripey cat named Nacho is crawling along the top of Mr. Bregar’s skull.  When it first starts crawling, it is traveling at 0.05 m/s (initial velocity).  It accelerates at 0.01 m/s2 until it is traveling at 0.12 m/s (final velocity).  For how much time did it accelerate?

 

4.         A big piece of chicken is thrown across the road.  Before it is thrown, it is motionless (its velocity is 0 m/s).  When it lands on the other side of the road, its velocity is 5.6 m/s.  If it was in the air for 7.5 seconds, what was its acceleration?  Use the Five Steps.

 

5.         A ferocious dog named Riley is chasing a pigeon down the street.  If Riley starts running at 4.8 m/s and over a time of 11.5 seconds accelerates at 1.14 m/s2, what will her final velocity be?  Use the Five Steps.
