A car is traveling due East at a rate of 36.2 kph and a train is due North at a speed of 74.70 kph and bound to meet at an intersection 1 km for the train and the car. a. Determine the acceleration of the car, If the car reaches the intersection 10 seconds ahead of the train. b. Determine the velocity of the car at the intersection.

Two trains are 900.0 kilometers apart. One is in Portland. The other is in San Francisco. They both begin traveling toward each other at the same time. The Portland train travels with an average velocity of 80.0 km/hr South. The San Francisco train travels North with an average velocity of 65.0 km/hr North.a. At what time will the two trains meet?b. How far away will they be from Portland when they meet?

The figure shows the speedometer readings as a car drives down a straightroad. (attached) a. What is the acceleration at t = 8.0s. b. What is the change in the cars speed from 5-10 seconds? c. What distance is traveled by the car between t = 0 and t = 4 s d. Draw a graph of the acceleration for the cars motion between t=0s and t=14s

At 10:17 a.m., you pass a police car at 55 mph that is stopped on the freeway. You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.

When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.
