Answer:
100m/s
Step-by-step explanation:
force(f) = 50N
weight = 25N
weight = mass × gravity
25 = m × 10
25 = 10m
m = 25/10
m = 2.5kg
time(t) = 5sec
impulse formula
ft = m(∆v)
by substituting
50 × 5 = 2.5∆v
250 = 2.5∆v
∆v = 250/2.5
∆v = 100m/s
i hope this helped
Force = 50N
Weight = Mass × Gravity = 25
Mass = 25 ÷ 10 = 2.5Kg
Time = 5 Seconds
we know
Force = mass × acceleration
50 = 2.5 × Velocity ÷ Time
50÷2.5 = Velocity ÷ 5
Velocity = 250 ÷ 2.5
Velocity = 100m/s.
