What are the magnitudes of (a) the angular velocity, (b) the radial acceleration, and (c) the tangential acceleration of a spaceship taking a circular turn of radius 2840 km at a speed of 18500 km/h

(a) 6.51rad/h≈1.03rev/h

(b) 120500km/h²

(c) Zero

Explanation:

The angular velocity of an object in circular motion is given by:

So the angular velocity has magnitude 6.51rad/h, roughly 1.03rev/h (a).

The radial (centripetal) acceleration is given by:

In words, the radial acceleration is roughly equal to 120500km/h² (b).

Since the spaceship is describing a circular motion with constant speed, the magnitude of the acceleration parallel to its velocity is zero (because its speed isn't changing). So, the magnitude of the tangential acceleration is zero (c).

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
