Question

C- The plot 3.5 2.5 1.5 0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 t (s) shows the positions of two cars A (the red line) and B (the blue line). At what time is the velocity of A and B the same? O 0.714s O They never have the same velocity O 1.43 s You see some people playing horseshoes; you have never played before so you ask if you can try. They let you, but when you go to release the horseshoe you release it late and it ends up going straight up into the air. What is its acceleration as it reaches its highest point? O more than g less than g O equal to g

Explanation / Answer

(c) Slope of x-t graph gives velocity. As we can see slope of car A and B are different they have different velocity. So "They never have same velocity"

(d) Whenever any particle is in air only gravitational forcr acts on it which gives acceleration g. So acceleration of horseshoe is " equal to g"
