Using 2nd equation of motion
h = ho + ut - 0.5 gt^2
0 = ho + 26 *19 - 0.5*9.8* 19^2
ho = 1274.9 m
8.
ho = 1274.9 + 26^2/2 x 9.8
ho = 1309.39 m

9. A speeder traveling at 42 m/s passes a motorcycle policeman at rest at the side of the road. The policeman accelerates at 3.23 m/s2. To the nearest tenth of a second how long does it take the policeman to catch the speeder? 10. How far to the nearest tenth of a meter can a runner running at 12 m/s run in the time it takes a rock to fall from rest 56 meters?
A police car is traveling at a velocity of 18.0 m/s due north, when a car zooms by at a constant velocity of 48.0 m/s due north. After a reaction time 0.300 s the policeman begins to pursue the speeder with an acceleration of 4.00 m/s^2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
A police car is traveling at a velocity of 18.0 m/s due north, when a car zooms by at a constant velocity of 48.0 m/s due north. After a reaction time 0.600 s the policeman begins to pursue the speeder with an acceleration of 3.00 m/s^2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
A police car is traveling at a velocity of 19.0 m/s due north, when a car zooms by at a constant velocity of 40.0 m/s due north. After a reaction time 0.500 s the policeman begins to pursue the speeder with an acceleration of 4.00 m/s^2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
1. A runner dashes from the starting line (x0) to a point 98 m away and then turns around and runs to a point I19 m away from the starting point in 21 seconds. To the nearest tenth of a mis what is the average speed? 2. What is the runner's average velocity in the previous problem? 3. A car accelerates at a constant rate from zero to 33.5 m/s in 10 seconds and then slows to 16.4 m/s in...
2. A police car is traveling at a constant velocity of 20.0 m/s due north, when a car zooms by at a constant velocity of 45.0 m/s due north. After a reaction time of 0.800 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s?. Including the reaction time, how long does it take for the police car to catch up with the speeder? Sketch the position vs time plot for the two motions and show...
Please explain! Chapter 02, Problem 85 Review Int a velocity of 17.0 m/s due north, when a car zooms by at a constant velocity of 41.0 m/s due north. After a reaction time 0.800 s the policeman begins to pursue the speeder with an acceleration of 3.00 m/s 2. Including the reaction time, how long does it take for the police car to catch up with the speeder? ingWare 2.2 in preparation for this problem. A police car is traveling...
5. A car starting from rest moves in a straight line with a constant acceleration of 2.20 m's for 100 s,then slows down to a stop with a constant deceleration of 3.05 m/s. How far does it travel? meters 6. Two cars are traveling along a straight road. Car (A) maintains a constant spoed of 900 kmh: car (B) maintains a constant spoed of 101 km/h. Att0, car (B) is 450 km behind car A. How far will car (A)...
A speeder is driving his car at a constant speed of 35.0 m/s on a wet one-lane highway. He then enters a tunnel and observes a slow driving truck 135 m ahead traveling at 4.00 m's. He applies his brakes and accelerates at -2.00 m/s. At what time do they collide? How far into the tunnel do they collide? a. b. e hat is the mini lin Bbtne beh uchsder wohyeato the brakes to prevent from colliding with the truck?
2. A car accelerates along a straight road from rest to 90 km/h in 5.0s. What is the magnitude of average acceleration in meters per second squared. 3. If you are driving 110km/h along a straight road and look to the side for 2.0s, how far do you travel during this inattentive period? 4. At highway speeds, a particular car is capable of accelerating at about 1.8m/s?. At this rate, how long does it take to accelerate from 80km/h to...
