Answer:
Some details are missing in the question, here are the details ; A proton initially has v = -6.5i + 17j + 13k and then 8.00s later has v = -2.8i + 17j - 9.3k (in meters per seconds).
a) proton's average acceleration in unit vector notation = 0.46i - 2.78k
b) Magnitude = 2.85m/s2
c) angle between and the positive direction of the x axis = 279.39 degree (counter clockwise)

PLEASE GIVE ME BRAINLIEST
Find volume
v=(1/3)hpir^2
r=60
h=210
pi=3.14 for this questio
v=(1/3)(210)(3.14)(60^2)
v=(1/3)(210)(3.14)(3600)
v=(70)(3.14)(3600)
v=(70)(3.14)(3600)
V=791,280 cm3
rate of 1099 er hour
drained out is zero
amount drained total=volume of cone=1099 times number of hours
lets say number of hours=x
1099x
791,280=1099x
divide both sides by 1099
720=x
answe ris 720 hours
