Q
Q: A 2 kg object is dropped from a height. What is the force acting on it just before it hits the ground? (2022)
Solution:
The force acting on the object is its weight, F = mg = 2 kg × 9.8 m/s² = 19.6 N.
Steps: 5
Show Steps
Step 1: Identify the mass of the object. In this case, the mass is 2 kg.
Step 2: Identify the acceleration due to gravity. On Earth, this is approximately 9.8 m/s².
Step 3: Use the formula for weight (force) which is F = mg, where F is the force, m is the mass, and g is the acceleration due to gravity.
Step 4: Plug in the values: F = 2 kg × 9.8 m/s².
Step 5: Calculate the force: F = 19.6 N.
