Suppose the odometer on our car is broken and we want to estimate the distance driven over a 30 second time interval. We take the speedometer readings every five seconds and record them in the following table. Time (s) 0 5 15 20 25 30 Velocity (mi/h) 17 21 24 29 32 31 28 In order to have the time and the velocity in consistent units, let's convert the velocity readings to feet per second (1 mi/h Time (s) Velocity (ft/s) DA 40+ 20- 0 5 25 40- 10 ft. If we add similar estimates for the other time intervals, we obtain an estimate for the total distance traveled. (25 x 5) + (31 x 5) + (35 × 5) + (43 × 5) + (47 × 5) + (45 × 5) = ft. 20- 10 35 During the first five seconds the velocity doesn't change very much, so we can estimate the distance traveled during that time by assuming that the velocity is constant. If we take the velocity during that time interval to be the initial velocity (25 ft/s), then we obtain the approximate distance traveled during the first five seconds. 25 ft/s x 5 s ft…
(7) Two cars (Car A and Car B) travel on parallel east-west roads (Road 1 and Road 2) located 10km apart. Car A is travelling west on Road 1 at a speed of 80km/h. Car B is travelling east on Road 2 at a speed of 50km/h. How fast is the distance between them changing, when the distance between them is 15km? Hint. Draw a picture to get started.
A circle is inside a square. The radius of the circle is decreasing at a rate of 1 meter per minute and the sides of the square are decreasing at a rate of 3 meters per minute. When the radius is 3 meters, and the sides are 18 meters, then how fast is the AREA outside the circle but inside the square changing? The rate of change of the area enclosed between the circle and the square is square meters per minute.
A car and a truck leave the same place and travel in the same direction along a straight road. The car starting from rest speeds up to 24 kph with a constant acceleration of 1/6 m/s² and then runs at this speed. The truck leaves 40 seconds after the car with a uniform acceleration of 1/3 m/s² from rest to attain a speed of 48 kph and then travels at this speed. How soon after the car started will the truck overtake the car?
Chemistry i need help! can u help me please?
A bus leaves a bus stop and accelerates at a constant rate for 10 seconds. During this time, the bus traveled 20 meters. Then the bus traveled at a constant speed for 10 seconds. Then the driver noticed his destination 10 meters ahead and slams on the brakes. Assume the bus decelerates at a constant rate. Eight seconds after the bus left the bus stop, a car passed by the bus stop travelling with constant velocity of 10 meters per second. How long (from the bus stop) will the car meet the bus? Express your answer in "seconds".
