6. A car travels along a straight line at a constant speed of AMT 60.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 30.0 mi/h. (a) What is the con- stant speed with which the car moved during the second dis- tance d? (b) What If? Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the same constant speed as found in part (a). What is the average velocity for this trip? (c) What is the average speed for this new trip?

Ih took Joseph 30 minutes longer to drive 375 km from along the north shore of a river from Apex to Rounder than it took to return along the south shore, a distance of 420 km. On the retum trip the highway was wider and in better condiftion, so he was able to average 10 km/h faster. What was his average speed on cach part of the trip?
a) A sprinter in a race accelerates uniformly for the first 65 m and then runs with constantvelocity. If the sprinter’s time for the first 65 m is 12 s, calculate his:i. acceleration, andii. final velocity for the race.
If acceleration is a function of displacement, integrate a ds = v dv to obtain the velocity as a function of position. O True OFalse
You can accelerate and brake on your bicycle with a maximum magnitudeof the acceleration of 3 (m/s)/s. Your top speed is 12 m/s. You want to drop ofyour physics textbook at your friend who normally works with an electronictextbook version, but just called and asked you for your printed copy for theafternoon. She lives 168m up the road from you. You need 11 seconds to runout of your apartment and grab your bike, and you need another 11s to run toyour friend’s apartment door to hand her the book after stopping with your bike.How long to you need in total to bring her the book?

A sports car starts from rest at an intersection and acceleratestoward the east on a straight road at 8.0 m/s2. Just as the sportscar starts to move, a bus traveling east at a constant 18 m/s on the samestraight road passes the sports car. When the sports car catches up withand passes the bus, how far has the sports car traveled?
A turtle crawls along a straight line, which we’llcall the x-axis with the positive direction to the right. The equationfor the turtle’s position as a function of time is x 1t2 = 50.0 cm +(2.00 cm/s)t - (0.0625 cm/s2)t2. How long after starting does it take the turtle to return to its starting point?
A particle moves in a straight line withe a constant acceleration of 4.05 m/s2 in the positive direction. If the initial velocity is 2.23 m/s in the positive direction, then how long, in seconds, does it take to move 7.66 m? And what is the particles final velocity in m/s?
