Push-up Puntos: 20 Misako is about to do a push-up. Her center of gravity lies directly above a point on the floor which is d₁ = 1.16 m from her feet and d₂ 0.69 m from her hands. If her mass is 53.0 kg, what is the force exerted by the floor on her hands? = d1 Center of gravity d2 Enviar Respuesta Tries 0/40 What is the force exerted by the floor on her feet?

Sphere in a Wedge Puntos: 20 A sphere of mass 8.0 kg rests in a groove, as shown in the figure below. The angle between the surfaces is 0 32.0°. Assume no friction and take the weight of the sphere to act at its center. The angle shown in the figure is not to scale. B Compute the magnitude of the reacting force at point A.

Mass Attraction Puntos: 20 2.4 kg and M₂ Two isolated masses, M₁ 633.0 kg are initially at rest, a distance d= 171.0 cm apart. Their gravitational attraction is the only force acting. Calculate the time it takes for M₁ to move from that distance to 169.0 cm from M₂. Assume that M₂ does not move and that the force is constant over that small distance, and equal to that at 170.0 cm. 1.50*10^-8m/s^2 = Enviar Respuesta Unidades incompatibles.
