First find the direction velocity
Vo =
tan θ = vy/vx = 10/30 = 1/3
so, sin θ = 1/√10 = √10/10
and time to reach further point is same with how long the ball in the air
Sorry for bad english (from Indonesian)
D = m/v
2.7 = 3/x
2.7x = 3
x = about 1.11
Answer:
Difference: The weak force tears an atomic nucleus apart.The strong force is what keeps the protons and neutrons in a nucleus held together, while the weak force is what makes radioactive particles decay.Or even simpler: The strong force keeps stuff together while the weak force helps stuff split up.
Similarities: Weak force allows quarks to turn into other quarks, which can turn a neutron into a proton and break up the nucleus. ... One big difference is that the particles/fields that are responsible for carrying the strong force are massless, whereas for the weak force they are quite massive (nearly 100 times the proton mass).
60,000 is 100 times as much as 600
