- Jeff Bezos just landed on the moon and is conducting an experiment, he drops a hammer from rest from a height of 2.01 m and uses a stopwatch to measure that the hammer takes 1.04 s to hit the ground. 1) Determine the magnitude of the acceleration due to gravity on the moon. 2) he then throws the hammer straight up into the Martian sky. If it comes back to his hand in 4.20 s, with what speed did he throw it?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 car traveling 52.7 km/h is 24.2 m from a barrier when the driver slams on the brakes. The car hits the barrier 1.93 s later. (a) What is the car's constant deceleration magnitude before impact? (b) How fast is the car traveling at impact?
- A Ferrari traveling well over the posted speed limit, passes a parked Tennessee State Trooper who decided to give chase. It takes the trooper 4.6 seconds to turn on the 'blue lights' and get the 'at rest' PW5000 powered Dodge interceptor moving. Then 8.3 seconds more to accelerate to its top speed and 63 seconds more to catch up with the speeder 3.5 km down the highway from the trooper's parking spot. Determine the average speed of the Ferrari over this distance in km/hrA car was traveling at 33.0 m/s on a poorly lit country road. The driver started to brake 0.35 seconds after he sees that a bridge is under construction 75 meters ahead. The car slowed down uniformly. What must be the minimum acceleration be to avoid crashing into the construction?At 5:11 p.m. in the highway and at the height of a town, a police patrol was traveling at a speed of 18.0 m / s towards the city, when the citizen's car approaches a speed of 94 mi / h towards the city. After a reaction time of 0.800 seconds, the police start chasing the citizen with an acceleration of 5.00 m / s2. Including the reaction time: (a) How long does it take for the police patrol to reach the citizen? (b) Indicate how far it reaches, from the moment the chase begins, and create a Position vs. time graph, showing the two movements (that of the citizen and the police patrol)
- The patient attends physiotherapy procedures at the clinic every day. Every morning he leaves the house at the same time and moves at a constant velocity 2,5 km/h. Once, leaving the house on time, the patient, on the 1/2 part of the way, remembered that he had forgotten the documents at home and decided to return home. How fast does the patient have to move in order to be in time for the beginning of the procedure? Please enter the correct units of measurement.Freight trains can produce only relatively small accelerations and decelerations. a) What is the final velocity of a freight train that accelerates at a rate of 0.0418 m/s² for 6 min, starting with an initial velocity of 3.22 m/s?Ilya and Anya each can run at a speed of 7.60 mph and walk at a speed of 3.50 mph .

Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half. a) Find Anya's average speed. b) How long does it take Ilya to cover the distance? (in minutes) c) Now find Ilya's average speed. Thanks
- Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?A family drives on a trip to visit their relatives. On the first day they travel 550 miles with an average speed of 50 mi/hr, on the second day 420 miles with an average speed of 35 mi/hr and on the third day 585 miles with an average speed of 45 mi/hr. a) What is the total driving time? b) What is the average speed for the trip?A car is initially traveling at 60.9 km/h. The brakes are applied and the car stops over a distance of 23.6 m. What was magnitude of the car's acceleration while it was braking?
