the speed time graph of Two cars represented by p and q as shown in figure 46 find the difference in the distance travelled by the two cars in m after 4 second do the ever move with the same speed if so when what type of motion car p and car q undergoing?
Answers
Given : the speed time graph of Two cars represented by p and q
To find : the difference in the distance traveled by the two cars in m after 4 second . do they ever move with the same speed
Solution:
Distance covered = area under curve
Distance covered by P = (1/2) *4 * 6 = 12 m
Distance covered by Q = 4 * 3 = 12 m
Hence there is no Difference in distance traveled in 4 mins
Another method
Distance by P = ((0 + 6)/ 2) * 4 = 12 m
Distance by Q = ((3 + 3)/ 2) * 4 = 12 m
there is no Difference in distance traveled in 4 mins
Speed of Car P at at 2 Sec = 3 m/s
Speed of Car Q at at 2 Sec = 3 m/s
At 2 Sec they move with the same speed
Car P is moving with constant acceleration
Car Q is moving with Constant speed
