we need to see the answers but probably 1 or -1
Answer:
(av + bu) miles
Explanation:
Average speed = distance/time
distance = time × average speed
distance from the starting point to the beginning of the opposite direction = a hours × v mph (mph is miles per hour) = av miles
distance from the opposite direction to the end = b hours × u mph = bu miles
distance from where he started to the end = (av + bu) miles
Answer:
4.9 m/s
Explanation:
Since the motion of the ball is a uniformly accelerated motion (constant acceleration), we can solve the problem by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the ball in this problem,
u = 0 (it starts from rest)
is the acceleration
s = 3 m is the distance covered
Solving for v,
