Chapter 2, Problem 53P
In an action movie, the villain is rescued from the ocean by grabbing onto the ladder hanging from a helicopter. He is so intent on gripping the ladder that he lets go of his briefcase of counterfeit money when he is 130 m above the water. If the briefcase hits the water 6.0 s later, what was the speed at which the helicopter was ascending?

If he accidentally dropped one stone 1.0 s ahead of the other, with what initial velocity (in m/s) must the second stone would have to be thrown if the two stones would hit the ground at the same time? Note: The tower is 54 m high.

- A group of students celebrate their first year of medical school with a hot-air balloon ride, which is rising upward with a constant speed of 3.0 m/s. When the balloon is 3.50 m above the ground, one of the students who is taking a selfie with the other students accidentally drops her smart phone over the side of the balloon (fortunately with a OtterBox case). With what speed would the phone hit the ground in m/s? Note that the displacement of the phone dropping 3.50 m would be - 3.50 m. For the same situation as Question 9, how long in seconds would the smart phone be in the air before it hits the ground?arrow_forwardA car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?arrow_forward. A hot-air balloon is drifting straight downward with a constant speed of 2.40 m/s. When the balloon is7.63 m above the ground, the balloonist decides to drop one of the ballast sandbags to the ground below.How much time elapses before the sandbag hits the ground?arrow_forward
