b). 
Explanation:
For the block that stays on the track, its maximal height is attained when all of the kinetic energy is converted to potential energy
a).
The height for the block on the longer track can by find using this equation:
Cancel the mass as a factor in each element in the equation
b).
The other lost some kinetic energy so, use a projectile motion to determine the total height for the other bock:
Solve to v'

Explanation:
Answer:
7. 1ml = 20 drops
325ml = 6500
( 325 x 20 = 6500)
there are 6500 drops in a pepsi can
8. not sure sorry ; (
9. 1 mile per hour = 88 feet per minute
45 miles per hour = 3960 feet per minute
( 88 x 45 = 3960)
there are 3960 feet per minute in 45 miles per hour
Your answer:
150 kilometer's per hour.
1h----------------> 70x3=210 bacteria
2h-----------------> 210*3=630 bactaeria
let be y the number of bacteria at the t=0h
it is y=70 3^0
for t= 1h
y=70*3^1=210
for t=2h
y=70*3^2=630
so we can write y=70*3^x, where x is the number of hour
