A glacier can cause a change in landforms as it picks up rocks and moves the rock to new locations. How fast does the glacier have to be moving to impact local landforms?

30 meters/day.

Explanation:

Glacial motion can be fast up to 30 meters/day or slow up to 0.5 m/year on small glaciers moving the impact on local landforms. If the glacial motion goes up to 30 meters/day, more fast change occurs in the local landforms while on the other hand, if the glacial motion goes up to 0.5 m/year, very slow change occurs in the local landforms. So glacial motion has a direct affect on the changes occurs in the local landforms.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
