Answer:
9.8 m/s
Explanation:
The work done by the force pushing the cart is equal to the kinetic energy gained by the cart:
where
W is the work done
is the final kinetic energy of the cart
is the initial kinetic energy of the cart, which is zero because the cart starts from rest, so we can write:
But the work is equal to the product between the pushing force F and the displacement, so
So, the final kinetic energy of the cart is 480 J. The formula for the kinetic energy is
(1)
where m is the mass of the cart and v its final speed.
We can find the mass because we know the weight of the cart, 98.0 N:
Therefore, we can now re-arrange eq.(1) to find the final speed of the cart:
Answer:
A=3.33m/s
B=3.11m/s
Explanation:
Speed = total distance/time taken to cover distance
hence,
S=d/t
s=32.0/9.60
s=3.33m/s
acceleration due to gravity
v=u+at
that is (v=final velocity,u=initial velocity,a=acceleration and t= time)
from the formula
2.10=32.0+a*9.60
2.10=32.0+9.60a
CLT
9.60a=32.0-2.10
9.60a=29.9
a=29.9/9.60
a=3.11m/s
hope it correct!?
Answer:
8.64 m/s
Explanation:
v1 = 8 m/s, v2 = ?, P2 - P1 = 5338 Pa, density of water, d = 1000 kg/m^3
By the use of Bernoulli's theorem
P 1 + 1/2 x d x v1^2 = P2 + 1/2 x d x v2^2
P2 - P1 = 1/2 x d x (v2^2 - v1^2)
5338 = 0.5 x 1000 x (v2^2 - 64)
10.676 = v2^2 - 64
v2^2 = 74.676
v2 = 8.64 m/s
