. A boat is traveling 5 m/s and accelerates at a rate of 3 m/s 2 . How long will it take for the boat to reach a velocity of 20
1 answer:
Given :
A boat is travelling 5 m/s and accelerates at a rate of 3 m/s² .
u = 5 m/s.
a = 3 m/s².
To Find :
How long will it take for the boat to reach a velocity of 20 m/s.
Solution :
Final velocity is v =20 m/s.
By equation of motion :
Putting all given values :
Therefore, time taken to reach 20 m/s is 5 seconds.
Hence, this is the required solution.

Step-by-step explanation:
On Friday, there were x students at the baseball game.
On Monday, there were 1/2 as many students, that is: x/2 students
On Wednesday, there were 32 fewer students at the game as there were on Friday, that is x - 32.
Tickets are sold for each student. Therefore, the number of tickets sold on all three days will be the same as the number of students that were at the games on the three days.
The number of students present on the three days is:
x + x/2 + x - 32
The number of tickets sold can therefore be represented by
