Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 7.0-kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.25 m from the one remaining 1.5-kg bowling pin. Required:
Determine the force of gravity between the ball and the pin and comment on the efficacy of the technique.

.

Kramer could try blowing air on the bowling pin.

Explanation:

= Mass of bowling ball = 7 kg

= Mass of bowling pin = 1.5 kg

= Distance between them = 0.25 m

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

Force of gravity is given by

The force of gravity between the ball and the pin is .

Kramer could try blowing air on the bowling pin.

i think they are all correct

explanation:

they seem good
