A train is traveling down a straight track at 33 m/s when the engineer applies the brakes, resulting in an acceleration of -1.0 m/s2 as long as the train is in motion. How far does the train move during a 66-s time interval starting at the instant the brakes are applied? Enter a number swer is not zero. m Need Help? Read

A ball is thrown vertically upward with a speed of 25.0 m/s.(a) How high does it rise? (b) How long does it take to reachits highest point? (c) How long does the ball take to hit theground after it reaches its highest point? (d) What is itsvelocity when it returns to the level from which it started?

P13 A passenger train is traveling at 29 m/s when the engineer sees a freight train 360 m ahead, traveling in the same direction on the same track. The freight train is moving at a speed of 6.0 m/s. The reaction time of the engineer is 0.40s What is the distance between the trains when the engineer applies the brakes? What is the minimum (constant) rate at which the passenger train must lose speed if a collision is to be...

You are on a train that is traveling at 3.0 m/s along a level straight track
You are on a train that is traveling at 3.0 m/s along a level straight track. Very near and parallel to the track is a wall that slopes upward at a 12° angle with the horizontal. As you face the window (0.86 m high, 2.1 m wide) in your compartment, the train is moving to the left, as the drawing indicates. The top edge of the wall first appears at window corner A and eventually disappears at window corner B....

A train 350 m long is moving on a straight track with a speed of 83.9 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 15.2 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.

1. A 25,000-kg subway train initially traveling at 20 m/s slows to a stop in a station and then stays there long enough for its brakes to cool. The station's dimensions are 65 m long by 20 m wide by 15 m high. Assuming all the work done by the brakes in stopping the train is transferred as heat uniformly to all the air in the station, by how much does the air temperature in the station rise? Density kg/m2....

Constants Part A A 23000 kg subway train initially traveling at 14.5 m/s slows to a stop in a station and then stays there long enough for its brakes to cool. The station's dimensions are 65.0 m long by 20.0 m wide by 12.0 m high. Assuming all the work done by the brakes in stopping the train is transferred as heat uniformly to all the air in the station, by how much does the air temperature in the station...

Do the algebraic solution first before plugging in the values. 6. At the instant the traffic light turns green, an automobile starts with a constant accelerations s of 6.0 ft/s2. At the same instant a truck, traveling with a constant speed of 30 ft/s, overtakes and passes the automobile. a. How far beyond the starting point will the automobile overtake the truck? b. How fast will the car be traveling at that instant? 7. Two balls are thrown from the...
