Drawing a diagram of Paul’s trip we can see that his displacement is b + (–c) km east = (b –c) km east. B km displacement –c km (c) Distance = 5 km + 2 km = 7 km; Displacement = (5 km – 2 km) east = 3 km east. (a) From v d t v x.

T (b) v x.We want the answer in m/s so we’ll need to convert 30 km to meters and 8 min t to seconds: 30.0 km 1000 m 30, 000 m; 8.0 min 60 s 480 s. Then v x 30,000 m 63 m.1 km 1 min t 480 s s Alternatively, we can do the conversions within the equation: v x 30.0 km 1 km 63 m. T In mi/h: 8.0 min 60 s s 30.0 km 1 mi 18.6 mi; 8.0 min 1 h 0.133 h. Then v x 18.6 mi 140 mi.1.61 km 60 min t 0.133 h h 1 mi Or, v x 30.0 km 60 min 1 mi 140 mi.

At the beginning of the ride the elevator has to speed up from rest, and at the end of the ride the elevator has to slow down. These slower portions of the ride produce an average speed lower than the peak speed. Begin by getting consistent units. Convert 100.0 yards to meters using the conversion factor on the inside cover of your textbook: 0.3048 m = 1.00 ft. 1yard  1ftThen 100.0 yards 3ft 0.3048 m 91.4 m. From v d t d 91.4 m.

An alternative route is: Since v0 is upward, call upward the positive direction and put the origin at the ground.

The first answer corresponds to the candy reaching 4.2 m but not having gone over the top balcony rail yet. The second answer is the one we want, where the candy has topped the rail and arrives 4.2 m above the ground. Consider the subway trip as having three parts—a speeding up part, a constant speed part, and a slowing down part. Dtotal dspeeding up dconstant speed dslowing down.

Since Phil has only t Phil Phil Mala 13.6 s traveled 94.1 m when Mala crosses the finish line, he is behind by 100 m 94.1 m 5.9 m 6 m. 600 h 3-60. The time for Terrence to land from his maximum height is the same as the time it takes for him to rise to his maximum height.

Let’s consider the time for him to land from a height of 0.6 m. Taking down as the positive direction: From d v0t 1 at2 with v0 0 and a g d 1 gt2 2 2 t 2d 2(0.6 m) 0.35s. G 9.8 m s2 His total time in the air would be twice this amount, 0.7 s. V d 1 mi 80 mi.
