While curling, you push a rock for 2.50 m and release it when it has a speed of 1.60 m/s. It continues to slide at constant speed for 1.10 s and then hits a rough patch of ice. It finally comes to rest 7.40 m from where it was released. What was the curling rock's magnitude of acceleration after it hit the patch of rough ice?

A 1000kg helicopter hovers over a forest fire and starts to squirt water downward with a speed of 10m/s at a rate of 40kg/s. What is the initial upward acceleration on the helicopter when it first starts to release the water
Falcons are excellent fliers that can reach very high speeds by diving nearly straight down. To pull out of such a dive, a falcon extends its wings and flies through a circular arc that redirects its motion. The forces on the falcon that control its motion are its weight and an upward lift force—like an airplane—due to the air flowing over its wings. At the bottom of the arc, as shown, a falcon can easily achieve an acceleration of 15 m/s2. Suppose the falcon weighs 8.0 N and is turning with an acceleration of 15 m/s2 at the lowest point of the arc. What is the magnitude of the upward lift force at this instant?A. 8.0 N B. 12 NC. 16 N D. 20 N

At the bottom of the arc, as shown, a falcon can easily achieve an acceleration of 15 m/s2. A falcon starts from rest, does a free-fall dive from a height of 30 m, and then pulls out by flying in a circular arc of radius 50 m. Which segment of the motion has a higher acceleration?A. The free-fall diveB. The circular arcC. The two accelerations are equal.
A pole vaulter is momentarily motionless as he clears the bar, which is set 4.2 m above the ground. He then falls onto a thick cushion. The top of the cushion is 80 cm above the ground, and it compresses by 50 cm as the pole vaulter comes to rest. What is his acceleration as he comes to rest on the cushion?
The Cassini spacecraft traveled with a companion module, Huygens, that split off so that it could land on Saturn's moon, Titan. The acceleration due to gravity on the surface of Titan is 1.352 m/s?. If a piece of Huygens falls from a height of 1.40 m and lands on the surface of Titan, how long would the piece take to fall? Assume it starts from rest. 2.07 s 0.535 s 1.43 s 0.286 s
You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.0 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
