A passenger elevator travels from the first floor to the 60th floor, a distance of 210 m, in 35 s. What is the elevator's speed? - Answer-6m/s A motorcycle is moving at a constant speed of 40 km /h. How long does it take the motorcycle to travel a distance of 10km? - Answer-15m How far does a car travel in 0.75 h if it is moving at a constant speed of 88 km/h? - Answer-66km Describe the difference between average speed and constant speed. - Answer-Average speed is the total distance traveled divided by the total time of travel, while constant speed is neither slowing down nor speeding up staying the same. During a trip can a car's instantaneous speed ever be greater than its average speed? Explain. - AnswerYes, because instantaneous speed is at one point and the highest while average speed is the distance divided by the time. Michiko walked a distance of 1.60 km in 30 min. Find her average speed in m/s. - Answer-.9m/s A car travels at a constant speed of 30.0 m/s for 0.80 h. Find the total distance traveled in km. - Answer- 86km/s What is the momentum of a car with a mass of 1,300 kg traveling north at a speed of 28 m/s. - Answer- 36,400kg(m/s) north It has a momentum of 6.0 kg(m/s) south and a mass of 0.15 kg. What is the baseball velocity? - Answer- 40m/s south Find the mass of a person walking west at a speed of 0.8m/s with a momentum of 52 .0 kg(m/s) west. - Answer-65kgYou are walking toward the back of a bus that is moving forward with a constant velocity. Describe your motion relative to the bus and relative to the point on the ground. - Answer-My motion related to the bus is in the opposite direction and relative to the ground you are walking the speed of the bus minus the speed you are walking. What is the momentum of a 100-kg football player running north at a speed 4m/s - Answer-400kg(m/s) north Compare the momentum of a 6,300-kg elephant walking 0.11 m/s and a 50-kg dolphin swimming 10.4 m/s. - Answer-1 1/3 An Airplane starts at rest and accelerates down the runway for20s. At the end of the runway, it's velocity is 80m/s north. What is its acceleration? - Answer-4m/s2North A cyclist starts at rest and accelerates 0.5m/s2 south for 20s. What is the cyclist's final velocity? Yeah I guess... the high school of overreacting.. overthinkers - Answer-10m/s South Determine the change in velocity of a car that starts at rest and has a final velocity of 20 m/s north - Answer-The object has a constant velocity. A ball is dropped from a cliff and has an acceleration of 9.8m/s2. How long will it take the ball to reach a speed of 24.5m/s? - Answer-2.5s
