Answer:

the height of the is 6 m.

Explanation:

Given;

potential energy of the object, P.E = 50 J

Height of fall of the object, H = 12 m

Determine the mass of the object, m

P.E = mgh

m = (P.E) / (gh)

m = (50) / (9.8 x 12)

m = 0.425 kg

Let the height of the object at 25 J = h₂

mgh₂ = 25

h₂ = (25) / (mg)

h₂ = (25) / (0.425 x 9.8)

h₂ = 6 m

Therefore, the height of the object at 25 J is 6 m.

Ymorist [56]

Answer:440.03 N

Explanation:

Given

horizontal component of acceleration (a_x)=800 m/s^2

vertical component of acceleration (a_y)=880 m/s^2

mass of ball =0.37 kg

Force in horizontal direction=m\times a_x=0.37\times 800=296 N

Force in vertical direction =m\times a_y=0.37\times 880=325.6 N

Therefore net force is

F=F_x+F_y

|F|=\sqrt{296^2+325.6^2}

|F|=440.03 N
