Question 3 What is distance traveled when the body was moving with constant velocity?
Question 4 What is retardation of the body while slowing down?
Question 5 What is the distance travelled by retarding?
Question 6 What is the total distance travelled ?
Answers
Answer:
1) Based on wind resistance, for example, the terminal speed of a skydiver in a belly-to-earth (i.e., face down) free fall position is about 195 km/h (120 mph; 54 m/s).
2) Find the distance travelled during the period of acceleration. S=ut+12at2=4.0×5+12×1.2×52
3) The Distance Travelled By A Moving Body Is Directly Proportional To Time. Since acceleration is zero so speed 'u' of the object remains constant.
4) Retardation is nothing but a negative acceleration. The velocity of the body may either increase or decrease. Similarly, if the velocity decreases, the acceleration is said to be negative. The train reaching the station slows down, in this case, we can say that the train is retarding.
6) The distance travelled is the path taken by a body to get from an initial point to an end point in a given period of time, at a certain velocity. If the velocity is constant: Distance = time * velocity. d = v*t.
