- 1) A student drove to the university from her home and noted that the odometer reading of her car increased by 15.8 km. The trip took 25.9 min. a) What was her average speed, in meters per second? b) If the straight-line distance from her home to the university is 10.3 km in a direction 25° south of east, what was the magnitude of her average velocity in meters per second? c) If she drove back home using the same path she took out to the university and arrives 7.9 h after she first left home, what was her average speed for the entire trip, in meters per second?a train is traveling west at 60mile/h and at t=4s later it is traveling north at 60mile/h. find the average a(arrow) (/a(arrow)/ and theta). plot the a(arrow) on x-y graphThe formulas are in the picture. (The acceleration due to gravity is 9.8 m/s^2 because the formulas are already negative.) Please explain it in an easy to understand way and show what formulas you use too. Jason jumps his motorcycle off a 50m tall cliff. How fast does he have to go to land at his target 90 m from the base of the cliff? (assume no air resistance) A football is kicked at a 37 degree angle at 20 m/s. Calculate: a) max height b) time in the air c) horizontal range d) velocity at max height e) acceleration at max height. (Assume no air resistance.)
- On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 810 km/h in the south direction. Enter the x and y components of the velocity separated by a comma.Consider a coordinate system with Stephen's home as the origin for questions 7-9. Watch out for positive and negative signs! 7. Stephen rode his skateboard 5.0 km from his home to school. What is his displacement?please help ASAP (and if you could also draw a picture/representation, that'd be great) thank you so much!
- The horizontal distance or range (R) of an object thrown at an angle θ from the horizontal is represented by the equation below where v0 is the initial velocity as the object leaves the hand, in feet per second. If v0 = 2500 feet per second and θ is changed from 13° to 14°, use differentials to approximate the change in range, in feet.part 1 of 3 Consider the plot below describing motion along a straight line with an initial position of x0 = 10 m. 6T 5+ сл 4+ velocity (m/s) 3+ 2+ 1 0 -2- 123 456789 time (s) What is the position at 2 seconds?
