Answer:
a)Vr= 5 mph
b)Vr= 115 mph
Explanation:
Lets
your velocity ,u= 60 mph
velocity of truck ,v= 55 mph
When object are moving in opposite direction the relative velocity = u +v When object are moving in opposite direction the relative velocity = u - v
a)
Truck is moving in the same direction ,so the relative velocity
Vr= = u - v
Vr= 60 - 55
Vr= 5 mph
b)
Truck is moving in the opposite direction ,so the relative velocity
Vr= = u+v
Vr= 60 + 55
Vr= 115 mph
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).
Explanation:
Remember that moment before collision is equal to the moment after collision.

Plugging in our values,

C) accretionary-wedge complex.
Explanation:
The accretionary wedge complex is a thick accumulation of sediments and small tectonic blocks formed from materials scraped off subducting oceanic lithosphere at a convergent margin.
Space between the subducting plate and the less dense plate gets filled by sediments scraped off the subducting plate and this forms a wedge like sediment called the accretionary wedge.
- The accretionary wedge is invariably made up of materials found on the ocean floor.
- Under extreme conditions, some parts of wedge transforms into metamorphic rocks.
- The wedge is made up of: pelagic sediments, ocean floor basalts e.t.c
