Answer:
Force will increase 3 times
Explanation:
We know force is directly porpotional to acclereation, with the constant, m mass.
So if we mass is increased 3 times the force will increase 3 times.
Answer:
The maximum height reached is 413.27 m.
Explanation:
How long will it take for a body to reach its maximum height, knowing that it was thrown, vertically upwards, with a velocity whose value was 90 m / s?
initial velocity , u = 90 m/s
gravity, g = 9.8 m/s^2
Let the maximum height is h.
At maximum height the velocity v = 0
Use third equation of motion
The time taken is
Explanation:
The motion of the bullet is a uniform motion (=constant velocity), therefore we can use the following equation:
where
v is the speed of the bullet
d is the distance covered
t is the time taken
For the bullet in this problem,
d = 0.30 m is the distance travelled
v = 800.0 m/s is the speed
Solving for t, we find the time taken:
