Answer:
(a) 
(b) 
Explanation:
(a) Since a constant external force is applied to the body, it is under an uniformly accelerated motion. Using the following kinematic equation, we calculate the final velocity of the mass if it is initially at rest(
):
According to Newton's second law:
Replacing (2) in (1):
(b) In this case we have 
. So, we use the final velocity equation:
Answer: 0.145 seconds
Explanation:
Given that Roger Clemens could routinely throw a fastball at a horizontal speed of 119.7 m/s. How long did the ball take to reach home plate 17.3 m away
Since the speed is horizontal
Using the formula for speed which is
Speed = distance/time
Where
Speed = 119.7 m/s
Distance covered = 17.3 m
Time is what we are looking for
Substitute all the parameters into the formula
119.7 = 17.3/ time
Make time the subject of formula
Time = 17.3 / 119.7
Time = 0.145 seconds.
Therefore, it will take 0.145 seconds to reach the home plates
