An aircraft is initially moving with a velocity of +7.0 m/s and travels for 8.0 s with a uniform acceleration of +3.0 m/s². The pilot then applies the brakes, causing a uniform acceleration of 4.0 m/s². The brakes are applied for 2.0 s. 1) Find the aircraft's speed at the end of the braking period. 2) How far has the aircraft traveled during the whole process?

(b) What time interval is required if there is a tailwind with the same speed? (c) What time interval is required if there is a crosswind blowing at 35.0 km/h to the east relative to the ground?
A woman on a bridge 103 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 6.95 m more to travel before passing under the bridge. The stone hits the water 4.58 m in front of the raft. Find the speed of the raft. Number i Units
The car starts from rest and accelerates according to the relationship 0.001V2 + a - 3 = 0 It travels around a circular track that has a radius of 300 meters. Calculate the velocity of the car after it has travelled halfway around the track. What is the car's maximum possible speed?
A dog and her handler are at rest, and are facing each other at a distance of 40.0 m. On command, they run towards each other: the handler runs at a constant speed vp = 2.5 m/s, while the dog first runs with constant acceleration ad = 2.0 m/s 2 until she reaches her maximum speed of vd = 4.5 m/s. a) Calculate the time it takes the dog to reach her maximum speed. Choose t = 0 when the handler and dog start to run. b) Find the positions of the handler and dog at the instant the dog reaches her maximum speed. Choose the coordinate, such as that the handler is at the origin x = 0 at time t = 0. %3D %3D %3D Notes Comments

I need help with this problem A student in Physics 211 decides to do an experiment. They travel to a city and climb to the roof of a building that is 3.0 x 102 m tall. Then, at the same instant, they drop one rock while a second rock is thrown downward with an initial speed of 16 m/s. Assume both rocks experience negligible air resistance while falling. How much EARLIER does the thrown rock strike the ground? A) 1.1 s B) 1.5 s C) 1.4 s D) they land exactly at the same time
