Answer:
increasing the masses of the objects and decreasing the distance between them
Explanation:
F = GmM/d²
Their masses are in the numerator, increased mass increases the force
Their separation is in the denominator, shrinking distance increases the force.
Answer:
Explanation:
Formula for AVERAGE acceleration
is Final Velocity
is Initial Velocity
is Final Time
is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
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
Answer:
b)

(b)
Speed of the boat after 18 days:
(c)
Distance traveled in 18 days:
using the equation of motion
Under constant acceleration, we have average velocity over a time interval of duration satisfying
where are the plane's initial position and velocity (respectively) and are the plane's position and velocity (respectively) after 9.00 seconds. So
