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.
