Trying to figure this out
This question can be easily solved with newton's second law of motion.
F=ma
a=F/m
=8/0.8
=10m/s^2
Answer:
1 (pitcher), 2 (catcher), 3 (first baseman), 4 (second baseman), 5 (third baseman), 6 (shortstop), 7 (left fielder) 8 (center fielder), and 9 (right fielder)
Explanation:
There are nine fielding positions in baseball. Each position conventionally has an associated number, for use in scorekeeping by the official score
Answer:
Option C, The total momentum of the fragments is equal to the original momentum of the firecracker.
Explanation:
Kinetic energy of cracker cannot remain constant before and after explosion. It is so because in the process of burning and bursting some amount of kinetic energy is lost in the form of light and heat energy. While the total mass before and after the explosion remains constant due to which the momentum is conserved before and after the explosion
Hence, option C is correct
In order to completely describe a velocity,
you need a speed and a direction.
