Answer:
Time, t = 0.1143 seconds.
Step-by-step explanation:
Given that distance, d = 14m
From the equation;
d = 10 + 40t - 5t
d = 10 + 35t
Substituting the value of distance;
14 = 10 + 35t
35t = 14 - 10
35t = 4
t = 4/35
t = 0.1143 seconds.
The time needed for the ball to reach the 14-m distance is 0.1143 seconds.
The thrown ball will reach a 14-m distance after 0.114 seconds.
The relation given is:
d = 10+40t-5t
where, d = 14
In this case, we've to put the value of d into the relation and this will be:
d = 10+40t-5t
14 = 10 + 40t - 5t
Collect like terms
40t - 5t = 14 - 10
35t = 4
Divide both side by 35
35t/35 = 4/35
t = 0.114 seconds.
