Please show all work with an explanation.
Two highways intersect at right angles. From out point of view, Car A on one highway is 0.5 km from the intersection and is moving toward it at 96 km/hr, while car B on the other highway is 1 km from the intersection and is moving away from it at 88 km/hr. We would therefore call the position and velocity of car A to us to be
Position: ?⃗? ?? ?? = (0.5 ??) ?̂
Velocity: ?⃗? ?? ?? = (−96 ?? /ℎ? ) ?̂

Please show work. (from my calculus book when I was a student!) Two highways intersect at right angles. From out point of view, Car A on one highway is 0.5 km from the intersection and is moving toward it at 96 km/hr, while car B on the other highway is 1 km from the intersection and is moving away from it at 88 km/hr. We would therefore call the position and velocity of car A to us to be Position:...
Two highways intersect as shown in the figure. At the instant shown, a police car P is distance dP = 870 m from the intersection and moving at speed vP = 87 km/h. Motorist M is distance dM = 560 m from the intersection and moving at speed vM = 56 km/h. What are the (a) x-component and (b) y-component of the velocity of the motorist with respect to the police car? (c) For the instant shown in the figure,...

Please try to answer all questions and show work. Thank you. 1. A baseball player is warming up and tosses a ball straight up into the air. The ball travels up until it reaches some maximum height, and then falls back down to the player's hand. If we neglect air resistance, then the magnitude of the acceleration of the ball is? A. largest the moment after it leaves the players hand. B. smallgst the moment after it leaves the player's...
Part 2 (Choose 3 Nom TUTT I 1. A race car starts from rest and travels 400 meters in 5.2 seconds. When it crosses the finish line it has a final velocity of 140 m/s. a) What is the acceleration (a) of this car? b) How much time was spent traveling from 100 m/s to 140 m/s? c) If this car continued at this rate of acceleration, how long would it take for it to travel 800 meters? 2. A...
I need the answers with steps please! 10. A boy throws a ball with an initial velocity of 25 m/s at an angle of 30° above the horizontal. If air resistance is negligible, how high above the projection point is the ball after 2.0s? How long is it in the air, and how far does it go before hitting the ground? 11. A projectile leaves the ground at 150 m/s and reaches a maximum height of 0.57 km. If there...
