- A student drove to the university from her home and noted that the odometer reading of her car increased by 12.0 km. The trip took 17.9 min. a.If the straight-line distance from her home to the university is 10.310.3 km in a direction 28.028.0º south of east, what was her average velocity? (magnitude and direction south of east) b.If she returned home by the same path 6.50h after she left, what was her average speed for the entire trip?We first need to convert the period from days to seconds. (Pdays)(Ns/day) Ps Ps S = = SOn a fishing trip on Lesser Slave Lake you drive your motorboat north at 20.0 km/h for 30.0 minutes. After realizing that you passed your fishing spot, you turn south and travel at 35 hm/h for 10.0 minutes. Determine your average. a) speed for this trip. [24km/h] b) velocity for this trip. [ 6.3 hm/h, North]
- You and your friend each drive 50.0 km. You travel at 90.0 km/h. Your friend travels at 9 km/h. How long will your friend be waiting for you at the end of the trip?please answer all parts of the questionCompute 3.24 m +0.532 m to the correct number of significant figures. A. 3.7 m B.3.77 m C. 3.772 m D. 3.7720 m
- A car drives 3.25 km at 12.6 m/s then drives another 5000 m in 3.39 minutes. Find the a) total distance, b) total time, and c) average speed for the whole trip.US Airways flight leaves Philadelphia in the early evening and arrives in Frankfurt 8.05 hours later. The airline distance from Philadelphia to Frankfurt is about 6.6 x 103 km, depending to some extent on the flight path followed. What is the average speed of the plane, in kilometers per hour? Average speed = total distance covered99. Subject:- Physics If the car's speed decreases at a constant rate from 64 mi/h to 50 mi/h in 3.0 s, what is the magnitude of its acceleration, assuming that it continues to move in a straight line? Express your answer in miles per hour squared. a = VG ΑΣΦ ? mi/h²
- Mr. M gets on his bike and rides 11m in the direction of [E52S]. He then changes his direction to [W11N] and rides another 5.7m. a) What was his total displacement? b) What was his distance traveled?Cheetahs can accelerate to a speed of 20.0m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.8 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +x-direction point in the direction the cheetah runs. Express the cheetah's top speed vtop in miles per hour (mi/h). Vtop= ______________ mi/h Starting from a crouched position, how much time taccel does it take a cheetah to reach its top speed, what distance d does it travel in that time? taccel = ____________ s d=_____________ m If a cheetah sees a rabbit 129.0 m away, how much time ttotal will it take to reach the rabbit, assuming the rabbit does not move and the cheetah starts from rest? ttotal = _________ sv(m/s) The opposite figure shows the relationship between speed and 3 time. an object is in motion, the distance traveled by the object t(s) during (6s) in meters is equal to: 3 6
