Two soccer players start from rest, 41 m apart. They run directly toward each other, both players accelerating. The first player's acceleration has a magnitude of 0.45 m/s². The second player's acceleration has a magnitude of 0.44 m/s². (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run? (a) Number i (b) Number i Units Units

At a soccer practice, the players run sprints. They start at the goal, run 10 m toward the center of the field and then run back to the goal. Then they run 20 m toward the center of the field and back to the goal. Finally they run 30 m toward the center of the field, turn around, and run back to the goal again. One player times herself to try and beat her personal best time. She runs the first 10 m in 2.5 s and gets back to the goal in 2.8 s. Then she runs the 20-m sprint in 5.7 s and gets back to the goal in 6.7 s. She runs the final 30-m sprint in 12 s and gets back to the goal in 15 s. Define the positive direction as forward, toward the center of the field and consider what a position versus time graph of her motion would look like. Rank the sprints according to their slopes on the position versus time graph, from steepest positive slope to steepest negative slope. Rank from steepest positive slope to steepest negative slope. To rank items as equivalent, overlap them.

The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 57 km/s. lo the crow's great surprisc, a Klingon ship is 150 km directly ahead, traveling in the same direction at a mere 21 km/s. Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 4 5s The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant Hint: Draw a position versus time graph showing the motions of both the Enterprise and the Klingon ship. Let æn - 0km be the location of the Interprise as it returns from warp drive I low do you show graphically the situation in which the collision is "barely avoided"? Once you decide what it looks like graphically, express that situation mathematically. Express your answer to two significant figures and include the appropriate units. a = μA Value m s² Review |…

1) The motions of a car and a motorbike along a straight road are described by the velocity vs time graph provided below. The two vehicles are initially alongside each other at time t=0 s. The motorbike’s speed is 18.1 m/s and the time T is 59.9  s.  a) what distance has the motorbike travelled between 0 and T (in km)? b) What distance has the car traveled between 0 and T (in km)? 2) Which of these statements is true? a. At T, the car and motorbike are at the same location. b. the acceleration of the car is constant between 0 and T  c. the acceleration of the motorbike is 0 d. the acceleration of the car is 0  3) a)What is the car's average speed for the first T seconds? (in m/s) b) What is the motorbike's average speed for the first T seconds (in m/s)

Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till  it was eliminated and c) the average velocity of the fly? how can i find this please

A distance of 60 meters separates two jetskis at Virginia Beach. Starting at rest, the jetskis accelerate at a constant rate of 0.2 m/s2 towards each other.Starting at a midpoint between the two jetskis, a porpoise is seen swimming from one jetski to the other at a constant speed of 16 m/s. The porpoise continues swimming back and forth between the jetskis until they crash together.a) What is the total distance the porpoise travelled? b) what is the speed of the jetskis when they crash together?
