Question 6 (1 point) The total mass of Bob and his bicycle is 79.3 kg. Bob is riding his bicycle at a speed of 16 23 m/s. He slows to a speed of 8.05 m/s in 66.4 s. How far does he travel during this time? Give your answer in metres. Your Answer
Question 9 (1 point) An airplane, with the mass of 5,713 kg, is about to take off. It taxis 2.28 km [E], then 1.52 km [N], then 4.14 km [W] on the runway before it takes off. From the beginning of taxiing it takes 42.5 min until the airplane takes off. What is the average speed of the airplane in km/h? Enter your answer up to 5 decimal places.
Consider an airplane whose takeoff speed is 225 km/h and that takes 16 s to take off at sea level. For an airport at an elevation of 1600 m (such as Denver), determine the following: a. The takeoff speed b. The takeoff time c. The additional runway length required for this airplane
Bob starts riding his bicycle from a stopped position. When he starts pedaling, the net force on the bicycle is 37.2 N. The mass of Bob and his bike is 72.63 kg. What is his speed 12.1 s later? Give your answer in m/s. Enter your answer up to 5 decimal places. Do not enter units.
Question 2 (1 point) Bob drives his car 145.00 km [N], then he stops to get gas. Then he drives his car 101.00 km (E), and stops to eat doughnuts. The he drives his car 239.00 km [S], and his journey ends. Bob's trip is completed in a time of 10.6 hours. The mass of his car is 1,673 kg. What is Bob's average speed in km/h? Enter your answer up to 5 decimal places. Do not enter units. Your...
Bob is sitting in his car at a red light. The car is not moving. When the light turns green, he takes his foot off the brake and the net force on the car becomes 3,920.4 N. What is his speed 3.29 s later? The mass of his car is 1,649 kg. Give your answer in m/s.
Sam, whose mass is 80 kg takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 15 s. What is Sam's top speed? Express your answer to two significant figures and include the appropriate units. How far has Sam traveled when he finally coasts to a stop? Express your answer to two significant figures...
Sam, whose mass is 75 kg , takes off across level snow on his jet-powered skis. The skis have a thrust of 160 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 15 s . A: What is Sam's top speed? - I found the answer to be 17 m/s (can you check this for me?) B: How far has Sam traveled when he finally coasts to a stop?...
