Answer:
Option b is right.
Step-by-step explanation:
When an object is thrown upwards, the acceleration acting is acceleration due to gravity in a negative manner.
a = -32 ft/sec square
Initial velocity let it be u
Final velocity when it reaches maximum height is 0
Use the formula connecting, u, v, a and s
ft/sec
Hence we find that initial velocity is 226 ft/sec
Option b is right.
Answer:
Step-by-step explanation:
9(9m+3t) = 9 *9m + 9*3t
= 81m + 27t
The algebraic expression is 6(x+2)
Answer:
1/4
Step-by-step explanation:
5/5 - 3/5 = 2/5
4x = 5/5 = 1
x = 1/4 (= 0.25)
