Unfortunately, Len-Len wasn't able to catch the keys and therefore the bunch of keys went straight to the ground. If Macoy gave the keys an upward speed of 3 m/s and the keys reached the ground after Macoy threw the keys upward in 4 seconds, c. What is the keys' acceleration when it reached its highest point?d. What is the keys' velocity when it reached its highest point?
- The motion of a cart can be represented by x (t) = (-2.5m/s) t – 10.0m. At what time does this cart cross the origin? It crosses the origint = 4s after we start observing it O It crosses the origin t = Os after we start observing it O If it were moving the same way before we started observing it then it crossed the origin 4 seconds before we started counting.PROBLEMS 11.1◆ Speed addition. Darnell stands in a railroad coach that moves at speedc relative to the Earth. He tosses a tennis ball forward at speed c relative to the train.

Please help and explain in an easy to understand.John and Anna both travel a distance of 8 kilometeres. a) How long does it take John to cover the distance if he does half the distance at 6.3 kilometers per hour and the other half at 1.2 kilometers per hour? b) What is his average speed for the total distance? c) How long does it take Anna to cover the distance of 8.00 kilometers if she goes 6.3 kilometers per hour for 2/3 of the total time and 1.2 kilometers per hour for 1/3 of the time? d) what is her average speed for the whole trip?
- travelled, and the total time of travel. Situation 03. A Ford Territory and a Montero Sport are traveling in the same direction at 60.0 kph on a straight highway, parallel to each other, and the Territory is ahead of Montero by 248.90 kph. At a certain time, Territory decelerates uniformly at 2.50 m/s², whereas the Montero accelerates uniformly at 2.0 m/s2.At what distance measured from the initial position of Montero will it overtake Ford Territory. Situation 04. The acceleration of a particle moving along a straight line is a = Vs, where s is in meters If its nosition s-0 and velocity v-0 when it is at restHi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please break it down so I can understand. I tried to solve it how you guys did it but I keep getting another answer. Thank you!Rey, Rhea and Roy are 25-year old triplets who joined the Space Force of planet Arthos. Rhea and Roy are tasked to travel through space while Rey is tasked to observe Rhea and Roy's travel. Rey records the details of Rhea and Roy's motion as follows: 1. Roy and Rhea left Arthos at the same time. 2. Rhea moved with a velocity 2/3 for 3 years. Then, she travelled back to Arthos at another velocity B1 3. Roy moved with a velocity -3/4 for 4 years. Then, he travelled back to Arthos at velocity 32. 4. Roy and Rhea arrived Arthos at the same time. At that time, Rey is 35 years old. What are Rhea and Roy's ages when they arrived in Arthos?
