Question

You push a friend on a swing.

She (her body) has a mass of 50kg.
She (her body) ACCELERATES (goes faster) at a rate of 4/ms(2).
The FORCE you used to push her is.________

Answer 1

The force used to push your friend on a swing is 200 Newtons.

Step-by-step explanation:

To calculate the force used to push a friend on a swing, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, your friend's mass is 50 kg and her acceleration is 4 m/s². So, the force used to push her can be calculated as:

F = m × a

F = 50 kg × 4 m/s²

F = 200 N

Therefore, the force used to push your friend is 200 Newtons.
