a
Explanation:
its the heaviest and its putting out the same force as the lighter ones
The kinetic energy for a large vehicle is different from that of a smaller vehicle, assuming that the vehicles are travelling at the same speed and stopping the same distance. This is because for a larger vehicle the kinetic energy is higher, as the mass for a larger vehicle, is more than the smaller vehicle.
Answer:
Explanation:
Given
y(x) = x² + x ( x represents time in seconds )
A )
value of y at x = 2
= 2²+2 = 6 m
value of y at x = 5
= 5²+5 = 30 m
displacement = 30 - 6 = 24 m
Time duration = 5 - 2 = 3 s
average velocity
= displacement /Time duration
= 24 / 3 = 8 m /s
B ) For x changing from x to x plus ie for small change in x :
value of y at x = 2
= 5
For small change in x , the value of y will again be 5 so displacement during small change in x will be zero . Hence average velocity will be zero.
C )
y(x) = x² + x
dy / dx = 2x + 1
dy / dx represents instantaneous velocity
so when x = 2
instantaneous velocity = 2 x 2 +1
= 5 m /s
