Answer with Explanation:
We are given that
Initial speed=
a.
Final velocity of ball=
g is negative because the ball is going against to gravity.
Using the formula
a.The ball rise upto height 18.4 m
b.It take 1.94 s to reach its highest point.
c.Initial velocity=0,s=18.4 m
Using the formula
C does not represent a benefit, so that seems most logical.
A) they comprised.
B) at least ones listening
D) nothings wring with that
Answer: 25 km
Explanation: If it travels 25 km in 1 hour it is going 25 km/h meaning if its speed doesn't change for the next hour it will go another 25 km.
Answer:
4 m/s in negative acceleration
Explanation:
Acceleration = V- U/t
Where V is the final velocity
U is the initial velocity and t is the time given.
U = 65 m/s
V= 25 m/s
T= 10 seconds
Acceleration= (25m/s - 65m/s)÷10secs
= - 40/10
= -4m/s^2
Hence, it has a negative acceleration.
