Imagine a landing craft approaching the surface of callisto, one of jupiter's moons. if the engine provides an upward force (thrust) of 2880 n, the craft descends at constant speed; if the engine provides only 1944 n, the craft accelerates downward at 0.39 m/s2. what is the weight of the landing craft in the vicinity of callisto's surface?

Weight:

Mass:

Explanation:

If the craft descends at constant speed it means that the engine thrust equals the gravitational force of the craft as the acceleration equals zero, from Newton´s second law:

Where W is the weight of the craft.

For the second case with lower thrust:

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
