time to accelerate to 15.3 m/s
t = 15.3 / 1.50 = 10.2 sec
distance during which this acceleration occurs
d = v2 / 2a = 15.32 / 2 * 1.50 = 78.03 m
distance covered at full speed
D = 373 - ( 2 * 78.03) = 216.94 m
time taken to cover this at max speed
t = 216.94 / 15.3
t = 14.17 seconds
Therefore,
total minimum travel time
T = 14.17 + ( 2 * 10.2)
T = 34.57 seconds

You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building. Before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. One of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. They are unlikely to approve the...

Answer both for best answer 1. ) In April 1974, Steve Prefontaine completed a 10 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 7.85 km mark at a time of 25.0 . If he accelerated for 60 s and then maintained his increased speed for the remainder of the race, calculate his acceleration over the 60 s interval. Assume his instantaneous speed at the 7.85 km mark was the same as his overall...

10) Classes are canceled due to snow, so you take advantage of the extra time to conduct some physics experiments. You fasten a large toy rocket to the back of a sled and take the modified sled to a large, flat, snowy field. You ignite the rocket and observe that the sled accelerates from rest in the forward direction at a rate of 12.5 m/s2 for a time period of 3.50 s. After this time period, the rocket engine abruptly...
Please answer the following physic questions. Thank you! 1. A dog sees a flowerpot sail up and then back past a window 5.0 ft high. If the total time the pot is in sight is 1.0 seconds, find the height above the window that the pot rises. 2. An elevator ascends with an upward acceleration of 4.0 ft/s2. At the instant its upward speed is 8.0 ft/s, a loose bolt drops from the ceiling of the elevator 9.0 ft from...
