Answer
given,
mass of block (m)= 6.4 Kg
spring is stretched to distance, x = 0.28 m
initial velocity = 5.1 m/s
a) computing weight of spring
k x = m g


k = 224 N/m
b) 




c) 


d) 


e)


A = 0.682 m
Force =
=
F = 94.20 N
Answer:
a).11.546J
b).2.957kW
Explanation:
Using Inertia and tangential velocity
a).


Now using Inertia an w

average power=
b).
power=t*w
P=
P=2.957 kW
75 percent off of water and please water the light water and water water and then go back and please water pollution please 880m
Answer:
The unit of speed is m/s.
Answer:
C) unbalanced
Explanation:
Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
