Please show all work!
1. A train is traveling down a straight track at 20 m/s when the engineer applies the brakes, resulting in an acceleration of 21.0 m/s2 as long as the train is in motion. How far does the train move during a 40-s time interval starting at the instant the brakes are applied? 2.A balli thrown vertically upward with a speed of 25.0 m/s.(o) How high does it rise? (b) How long does it take to reach...

Using the kinematic equations, find the horizontal range (aka x-displacement) and the time it took for an object launched from a height of 5m with an initial velocity of 15m/s and at an angle of 20 to reach the ground. The object follows projectile motion. Ignore air resistance. Show all work. The answer given for the horizontal range is 23.4m and the time is 1.66s. However, when I try to calculate the time, I keep getting 0.52s. I used the...

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...

3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...
