Answer: 10.96secs
Explanation:
According to newton's second law
Force = mass × acceleration
F = ma
F = m(v-u)/t
Cross multiplying we have
Ft = m(v-u)
t = m(v-u)/F
Given F = 2600N m = 19,000kg v = 1.5m/s u = 0m/s
Substituting this values in the formula for the time we have
t = 19000(1.5-0)/2600
t = 28,500/2600
t= 10.96secs
Mmm tricky.
Since the velocity is constant, I'm going to assume there is no acceleration in any direction. This means there is no net force in the I or J forection!
Since there are 2 forces, both must be equal and opposite in direction to perfectly cancel each other out.
So the opposite of F1 is (-2N)I + (6N)J!
