This rocket started at rest on the lunch pad. At a certain point in the time, WATER with a mass of 2 kg was coming out of the rocket with velocity of 10 m/s. If the ROCKET has a mass of 5 kg, what is the velocity of the rocket?

A - 20 m/s
B -0.25 m/s
C 1000 m/s
D 4 m/s

Juan created a chart to him study for a test. which headings best complete the chart? x: transparent objects y: opaque objects x: opaque objects y: transparent objects x: high frequency waves y: low frequency waves x: low frequency waves y: high frequency waves

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground
