Velocity is a vector meaning it includes an objects speed and direction.
Answer:
1800 meters
Explanation:
Average speed=1.2 m/s
time= 1500 secs
Displacement = average speed × time
= 1.2 × 1500
=1800 meters
Is their a multiple choice to choose from I'm not sure the answer I got is even right.
That would be very helpful.
Answer:
B. There is a direct proportion between the mass and force listed in the table.
Explanation:
From the table, the values of force increases with increase in the value of mass.
if 5kg=25 N
Finding the contant of proportionality k;
k=25/5=5
thus M=k(F)...........where M is mass in kg and F is force in newton, then
M=5F
This show that for every value of mass, we get the value of Force if we multiply by a contant k=5
This means there is a direct proportionality relation between mass and force in the table.
Answer:
The speed it reaches the bottom is
Explanation:
Given: 
, 
Using the conservation of energy theorem
,
