There is a 250-m-high cliff at Half Dome in Yosemite National Park in California. Suppose a boulder breaks loose from the top of this cliff. (a) How fast will it be going when it strikes the ground? (b) Assuming a reaction time of 0.300 s, how long will a tourist at the bottom have to get out of the way after hearing the sound of the rock breaking loose (neglecting the height of the tourist, which would become negligible anyway if hit)? The speed of sound is 335 m/s on this day.

Yosemite National Park in California. Suppose a
boulder breaks loose from the top of this cliff.
(a) How fast will it be going when it strikes the

s, how long a time will a tourist at the bottom
have to get out of the way after hearing the
sound of the rock breaking loose (neglecting the
height of the tourist, which would become

335.0 m/s on this day.
The engineer of an intercity train observes a rock slide blocking the train's path 550 m ahead and activates the train's emergency brakes. The train decelerates uniformly (Hint: negative acceleration) at 1.7 m/s and completely stopes just before hitting the rock. What is the initial speed of the train measured in m/s?

- A drag racer accelerates from rest at an average rate of +13.2 m/s2 for a distance of 100. m. The driver coasts for 0.500 seconds and then uses the brakes and parachute to decelerate until the end of the track.

The car reaches the dog 7.40 s later, and the dog jumps off the track just in time. If the car travels 3.80 m beyond the position of the dog before coming to a stop, how far was the car from the dog?
