Formula:
F = ma
m = F÷A
m: mass F:force A: accelerarion
m = 450N ÷ 15m/s^2
= 30kg
Hope this helps :)
Answer:
A is correct
Explanation:
The vertical force up is balanced by the vertical component of the largest force
The horizontal force to the right is balanced by the horizontal component of the largest force.
C and D will both tend to accelerate upward at some angle
B looks like the horizontal force right is larger than the sum of the horizontal components of the other two forces.
As kmoefgthdyfjkhyutgfrdescfgvh
Time = Distance / speed
Time = 2.5 km / 23 km/h
= 0.1087 hours 1 hour = 60 minutes
= 0.1087 * 60 minutes
= 6.522 minutes.
To solve this problem with the given elements we will apply the linear motion kinematic equations. We will start by calculating the time taken, with the vertical displacement data. Subsequently, with the components of the acceleration, we will obtain the magnitude of the total acceleration, to finally obtain the horizontal displacement with the data already found.
PART A) From vertical movement we know that the acceleration is equivalent to gravity and the displacement is 8m so the time taken to carry out the route would be

Here,


Replacing,


PART B) Now, Magnitude of acceleration



Thus, magnitude of net acceleration

PART C) Finally the displacement along horizontal direction is:



Therefore the distance traveled along the horizontal direction before it hits the ground is 3.098m
