Mr. gewanter, whose mass is 60 kg, is doing a physics demo in front of the classroom. how much gravitational force does he exert on 55 kg martha, 1.5 meters away?

F  = 9.79 x 10⁻⁸ newton

Explanation:

Given,

The mass of Mr. Gewanter, M = 60 Kg

The mass of Martha, m = 55 Kg

The distance between them, d = 1.5 m

The gravitational force between them is given by the formula

                                      F = GMm/d²  newton

Substituting the given values in the above equation

                                     F = (6.673 x 10⁻¹¹ x 60 x 55)/1.5²

                                        = 9.79 x 10⁻⁸ newton

Hence, the gravitational force acting on Martha due to Mr. Gewanter is, F  = 9.79 x 10⁻⁸ newton

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
