The speed of the solar wind is approximately 400 km/s and the distance from the Sun to Saturn is 9.5 AU (1 AU = 1.5 × 10^8 km). How long does it take a particle in the solar wind to reach Saturn?
a. about 4.1 hours
b. about 4.1 days
c. about 41 days
d. about 4.1 years
e. about 41 years
c
RATIONALE: Using conversions, you can set up an equation like t = d / v = 9.5 × 1.5 × 10^8 km / 400 km/s to obtain the time in seconds and then convert the time to days.

Equilibrium: As shown in the figure, a uniform rectangular crate 0.40 m wide and 1.0 m tall sits on a horizontal surface. The crate weighs 460 N, and its center of gravity is at its geometric center. A horizontal force of magnitude F is applied at a distance h above the floor. Friction at the floor is great enough to prevent the crate from sliding. If h = 0.69 m, what minimum value of F is required to make the crate start to tip over?
