Speed = Distance Time Velocity = 1. Find the velocity of a truck that travels 75miles north in 2.5 hours? List: Equation: Substitution: Answer with units:
Answer:
187.5 m/s (i think)
Explanation:
If you use the formula V= T times displacement you can find this out by doing the following-
Displacement equals 75 m
T equals 2.5 hrs
75x2.5= 187.5
and since velocity is measured in m/s, it becomes
187.5 m/s
pls help, i really dw fail :(
Answer:
Using the Newton equation
V²=U² +2as
Given; V=9.2m/s U = 0m/s( because it starts from rest)
S=26.2m.
9.2²=0²+2(26.2)a
a =9.2²/2(26.2)
a=84.6/52.4
a=1.60m/s²
Answer:
2.A
3.D
Explanation:
HOPE THIS HELPS!! :)
you do no know an objects velocity until you know its _____.
