Answer:
s = 22.5 m
Step-by-step explanation:
the equation for the speed change of a coach moving along a straight section of the road and starting braking at a speed of 20 m / s has the form v (t) = 25-5t. Using integral calculus, determine the coach's braking distance.
v (t) = 25 - 5 t
at t = 0 , v = 20 m/s
Let the distance is s.
Let at t = t, the v = 20
So,
20 = 25 - 5 t
t = 1 s
So, s = 25 x 1 - 2.5 x 1 = 22.5 m
Answer:

Step-by-step explanation:
Answer:
square root of 169 =13
Step-by-step explanation:
distance between 2 points is given by the square root of (144+25)
Length of rope bought by Sean = 68 3/4 inches
= 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
= 275/(4 * 15)
= 275/60
= 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope
the procedure and the method of solving is absolutely clear to you. This is the
easiest way to get to the solution for such problems.</span>
