So what you need to do before entering a curve is slow down. What is the safest way to enter a curve when driving? Suppose, for example, that the track has a radius of $3.0 \mathrm{m}$ and that the driver goes past point 1 at the bottom with a speed of $15 \mathrm{m} / \mathrm{s}$. This driving strategy will reduce the severity of a curve and the risk of skidding. The radius of the container is $12 \mathrm{cm}$ When the cylinder is rotating at 2.0 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall? One of the first things you must learn when driving in residential, suburban and urban neighborhoods is that not all traffic lanes are designed to be used in the same way. There is a clever kitchen gadget for drying lettuce leaves after you wash them. A rocket is used to place a synchronous satellite in orbit about the earth.

Sometimes a vehicle will understeer, a type of skid that happens when the vehicle turns sharply and begins to slide on the slick sidewalls of the tires. The radius of the planet is $4.15 \times 10^{6} \mathrm{m} .$ What would be the true weight of the satellite if it were at rest on the planet's surface? The station's purpose is to physically prepare astronauts for the transition to the different gravitational forces they will experience on Mars and the moon, but also to acclimate them to Earth's gravity when they return. Express your answer in $\mathrm{m} / \mathrm{s}$ and $\mathrm{m} .$ p.h. In this situation, drivers may need to drop into a lower gear and accelerate or brake to maintain a safe speed. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle $(r=11.0 \mathrm{m})$ as the carousel turns.
