The acceleration is 12(m/s)/5.2s = 2.308m/s^2
F=ma, so
F=2200*2.308 = 5076.9N
P= mv
where p is momentum
m is mass
v is velocity
so it's given p= 100kgm/sec
v= 4m/s
so putting in the formula
100= m × 4
m = 25kg
Answer: False I think that is worded weird tho
Time = (distance) / (speed)
Distance = 3,000 km = 3,000,000 meters
Speed = 200 m/s
Time = (3,000,000 m) / (200 m/s)
Time = <em>15,000 seconds</em>
That's 4 hours 10 minutes
