A receiver on a football team runs 8.0 m (E) and then turns abruptly to run 12.0 m [S]. If the entire motion takes 5.0 s, determine the receiver's: (a) total distance travelled. [2] (b) total displacement. [2] (b) average speed. [2] (c) average velocity. [2]
a) Draw the motion diagram of the quarterback on coordinates A football quarterback runs 15.0m straight down the playing field in 2.50s (with a constant speed). He is then hit and pushed 3.00m straight backward in 1.75s with a constant speed. He breaks the tackle and runs straight forward another 21.0m in 5.20s (still with a constant speed). b) Calculate the average velocity of the quarterback for each three intervals and the average velocity of the quarterback for the entire...
In a relay race, each contestant runs a distance 26.0 m while carrying an egg balanced on a spoon, turns around, and comes back to the starting point. Edith runs the first distance 26.0 m in a time t1 = 20.7 s . On the return trip she is more confident and takes only time t2 = 14.8 s . a) What is the magnitude of her average velocity for the first distance 26.0 b) What is the magnitude of...
A football player runs for a distance d1 = 8.55 m in 1.33 s, at an angle of θ = 62.1degrees to the 50-yard line, then turns left and runs a distance d2 = 10.68 m in 2.19 s, in a direction perpendicular to the 50-yard line. The diagram shows these two displacements relative to an xy coordinate system, where the x axis is parallel to the 50-yard line, and the y axis is perpendicular to the 50-yard line. What...
In a relay race, each contestant runs a distance 24.0 m while carrying an egg balanced on a spoon, turns around, and comes back to the starting point. Edith runs the first distance 24.0 m in a time t1 = 19.5 s . On the return trip she is more confident and takes only time t2 = 14.7 s . A. What is the magnitude of her average velocity for the first distance 24.0 m ? B. What is the...
A marching band player walks directly north at a speed of 2.50 m/s for a time of 12.0 seconds, turns 35.0°to the east and walks at half that speed for another 15.0 seconds. What is the players total displacement and average velocity for the entire trip?
(0) A car runs 25.0 m straight towards East (positive direction) in 2.50 s. It then runs backwards towards West 5.00 min 1.0 s. Then the car runs forward again for another 40.0 m in 4.0.s. Calculate the car's average velocity for the entire motion. (10pts) (2) A high speed train starts from rest with an acceleration of 5m/s for 22s. What is the final velocity? (10pts) (3) A high speed train starts from rest with an acceleration of 5m/s²...
A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.
Page |2 3. A marathoner runs due east for 61.5% of the time, stops and rests for 6.5% of the time, and then runs due west for remainder of the time. The average eastward velocity has magnitude 12.5 miles/hour while the average westward velocity has a magnitude of 11.0 miles per hour. Find (a) the average speed, and (b) the average velocity for the entire race. (c) How far did he run for a total time 2 hours 20 min...
Jaya drives 340.0 m due east, which takes her 15 seconds. She turns and travels 540 m due north while traveling at a constant 27.1 m/s. Then she turns and travels 210 m due east, which takes her 11.0 s. a) Draw a diagram showing Jaya's path. Label the path length of each leg of the journey. Draw the total displacement vector on the diagram. b) What is the total elapsed time for Jaya's journey? c) What was the path...
