Answer:
40,000
Explanation:
Momentum is defined as mass*velocity, so a doubling of velocity means a doubling of momentum
A. 4.67 m/s²
u = 145 m/s
v = 75 m/s
t = 15 s
a = v - u / t
= 145 - 75 / 15
= 4.67 m/s²
Hope this helped...
Answer:OOF
just divide 22 N by 20 kg to get the acceleration in m/s2
I hope this is right-
