Answer:

⇒ 73.7 J = 15 kg × 9.8 m/s² × h

⇒ h = (73.7 J) / ( 15 kg × 9.8 m/s²) = 0.5 m

Find force,
9.8 m/s2 x 5.24 kg = 51.352 N

Find work,
51.352 N x 1.63 m= 83.70 N*m


Example:
To solve this given word problem we can first identify the given and the apt formula to use in this phenomenon: Given: Force = 4, 500 N = 4, 500 kg-m/s^2 Acceleration = 5 m/s^2

Formula: f=ma
Derivation: m = f/a
Solution:
1.
M = f/a

2.
M = 4,500 kg-m/s^2 / 5 m/s^2

3.
M = 900 kg


Hence, the object’s mass is 900 kg.
