A 15-kilogram cart is at rest on a horizontal
Sergio [31]
The most likely answer to this problem would be (1) more mass and more inertia.

A 15-kilogram cart at rest and a 5-kilogram box would make up a 20-kilogram cart and box that is at rest on a horizontal surface. The mass changed into something more, of course, as a result of combining the two object into one and by combining the two objects' mass, the inertia that it previously possessed as a cart by itself was increased when the inertia of the box was also combined to the cart.

What was the speed of a space shuttle that orbited Earth at an altitude of 1482 km?
gregori [183]

Answer:

v = 7121.3 m/s

Explanation:

As we know that the centripetal force for the space shuttle is due to gravitational force of earth due to which it will rotate in circular path with constant speed

so here we will have

\frac{mv^2}{r} = \frac{GMm}{r^2}

here we know that

r = orbital radius = 6370 km + 1482 km

r = 7.852 \times 10^6 m

also we know that

M = 5.97 \times 10^{24} kg

now we will have

v^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})}{7.852 \times 10^6}

v^2 = 5.07 \times 10^7

v = 7121.3 m/s
