Gravity

Applying forces to 1-kg grapefruit and 3-kg pumpkin

1 pts

Consider a 1-kg grapefruit and a 3-kg pumpkin. Now suppose that we apply forces to each object. We exert three times as much force on the pumpkin as on the grapefruit, perhaps 4 newtons on the grapefruit and 12 newtons on the pumpkin. Now apply newton's second law in each case to calculate the acceleration of each object

Grapefruit: a = (1)
Pumpkin: a = (2)
