Answer:
F = F2 - F1 where F is the net force upwards
F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N
Since there is a net force in the upwards direction the rocket should experience an upwards acceleration.
Answer:
4.03 m/s
Explanation:
Initial momentum = final momentum
(282 kg) (3.50 m/s) + (155 kg) (-1.38 m/s) = (282 kg) (1.10 m/s) + (115 kg) v
v = 4.03 m/s
Metric system. important because it saves us time due to the fact that we do not have to convert our units every time.
I think it is Letter D, because she already said what to make
Only first is kinetic.
So 2-3-4 are not
