Answer:
Explanation:
Given,
For the first rocket,
- Initial velocity of the first rocket A =
- Acceleration of the first rocket =
For the second rocket,
- Initial velocity of the second rocket B =
- Displacement of both the rockets A and B = s = 0 m
Fro the first rocket,
Let 't' be the time taken by the first rocket A for whole the displacement
Let be the acceleration of the second rocket B for the same time interval
from the kinematics,
Hence the acceleration of the second rocket B is -33.65\ m/s^2.
Answer:
d) the amount of work is the same whether the bag is moved all at once or in two stages, provided the total height lifted is the same in either case.
Explanation:
While moving the bag to the shelf in one shot we can say that the total work done is given as
here we know that
2H = total height raised by the bag
now when we raise the bag to first shelf and then move it to next shelf
then we will have
so the correct answer will be
d) the amount of work is the same whether the bag is moved all at once or in two stages, provided the total height lifted is the same in either case.
Answer:
It will take 29.31 seconds for the Boxster to catch the Scion
Explanation:
Given the data in the question;
lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A
the distance travelled by car A is
x = × t
where is the speed of the car and t is time
the distance travelled by car B before reaching car A will be;
x + x₀ = × t
Now lets replace x by × t
so
( × t) + x₀ =
× t
x₀ = ( × t) - (
× t)
x₀ = t ( -
)
t = x₀ / ( -
)
so we substitute
t = 170 m / (24.4 - 18.6)
t = 170 / 5.8
t = 29.31 s
Therefore; it will take 29.31 s for the Boxster to catch the Scion
