Answer:
t = 25 seconds
Explanation:
Given that,
Distance, d = 115 m
Initial speed, u = 4.2 m/s
Final speed, v = 5 m/s
We need to find the time taken in increasing the speed.
We know that,
Acceleration, 
....(1)
The third equation of kinematics is as follows :
Hence, it will take 25 seconds to increase the speed.

Answer:
Explanation:
The work done by the force to stop the ball will decrease the kinetic energy of it. so we can write
W = - ΔK. E
F.d = - (
)
As the final velocity is zero.
F = 
1. orbit (the missing one)
2. axis
a. summer, northern
b. winter, northern
4. equinox
