Answer:
average acceleration is 1.365 × 
m/s²
Explanation:
given data
initila speed u = -32.2 m/s
final speed v = 21.6 m/s
time taken t = 0.00394 s
solution
we get here average acceleration that will be express as
v = u + at ..........................1
put here value and we get
21.6 = -32.2 + a × 0.00394
solve it we get
a = 1.365 × m/s²
so average acceleration is 1.365 × m/s²
Answer: True
Explanation:
Because plants have an increase in vigar to grow
Mv + mv = 2mv providing each momentum is in the same direction.
1/2 mv^2 + 1/2 mv^2 = mv^2
Answer: negative acceleration
Explanation:
Acceleration is speeding up, the ball is slowing down making it negative acceleration
Depends on how strong you are. People can hit it anywhere between a few inches and 500 yards.
