Answer:
point c
Explanation:
the cart has accelerated and is at the lowest point on the path .
consider the acceleration due to gravity converting potential to kinetic energy

Answer:
Distance will be 49.34 m
Explanation:
We have given wavelength
Diameter of the antenna d = 2.7 m
Range L = 7.8 km = 7800 m
We have to find the smallest distance hat two speedboats can be from each other and still be resolved as two separate objects D
We know that distance is given by
So distance D will be 49.34 m
1,4,6
a bow is drawn back
a gun is loaded w/ a dart
a bungee cord is stretched
So,
GPE (graviational potential energy) = mass x g x height
GPE is depends on where zero height is defined. In this situation, we define h = 0 as the initial height.
The builder has gained 18.375 kJ of PE.
