3. A cart with mass of 30 kg is traveling with a velocity of 4.0 m/s. The cart then gains speed, achieving a new velocity of 10 m/s after 4
seconds. Calculate the magnitude of the net force acting on the cart.

Ajet plane flying 600 m/s experience an acceleration of 4.0 g when pulling out of a circular dive. what is the radius of curvature part of the path in which the plane is flying? a) 7100 m b) 650 m c) 9200 m d) 1200 m
