Answer:
<em>17 m/s west</em>
Explanation:
Runner 1 has velocity = 10 m/s west
runner 2 has velocity = 7 m/s east
From the frame of reference of runner 2, we can imagine runner 2 as standing still, and runner 1 moving away from him, towards the west with their combined velocity of
velocity = 10 m/s + 7 m/s = <em>17 m/s west</em>
Answer:
this may seem wierd but a hill
Explanation:
a hill if its steep enough and you have wings on a car or something could make you fly depending the weight wind would also help a stop light no a flat road could if you going fast enough wat movement is depending thiers your 4 options hopee you learned something
The answer is 27.03 I just multiplied the two numbers
Answer:
90 m
Explanation:
Acceleration, 
where v and u are final and initial velocities respectively, t is the time taken
Substituting 
for a, 4 m/s for u and 10 s for t then
1*10=v-4
v=14 m/s
From kinematic equations
Making s the subject then
