Spaceship 1 and spaceship 2 have equal masses of 300 kg they collide spaceship 1s final speed is 2 ms and spaceship 2s final speed is 1 ms in the same direction what is their combined momentum?
Momentum is mass multiplied by velocity. The momentum of the two ships would be 300 x 2 = 600 kgm/s and 300 x 1 = 300 kgm/s. So the combined momentum of the two ships would be 900 kgm/s.
What is the momentum for a 10 kg wagon that has a speed of 25 meters per second?
p = m . v p = 10 * 25 = 250 kgm/s
What is the weight of 5 kg mass?
to get weight multiply by acceleration of gravity which is 9.81 m/s/s. 5 x 9.81 = 49.05 kgm/s/s = 49.05 Newtons
What object has more momentum a car traveling at 10 kilometers and hours or a baseball pitched at 150 kilometers and hour?
car 1500 kilograms baseball 150 grams cars energy = 1/2 x 1500 x (10/3.6)2 = 5,787 joules baseballs energy = 1/2 x 0.15 x (150/3.6)2 = 130 joules (i worked it out for energy then noticed it said momentum) car = 1,500 x 10/3.6 = 4,166.67 kgm/s baseball = 0.15 x 150/3.6 = 6.25 kgm/s the car
How much force is needed to accelerate an object of mass 10 kilograms at a rate of 5 meters per second squared?
By Newton's Second Law: F = ma, and since both mass (10kg) and acceleration (5 m/s2) is provided. The magnitude of the force needed is simply 10 x 5 = 50 kgm/s2 or 50 newtons.
