A 900 kg vehicle moves around a curve with an incline of 20∘ at a speed of 12.5 m/s. If the curve has a radius of 50 meters, what normal force [N] will the vehicle experience? Note: It's moving on a banked curve(needs to be in Newtons)

If an astronaut takes an object to the moon the following is true (choose only one). a the mass will change but the weight will be the same. b both the mass and the weight of the object will be the same. c the weight will change but the mass will be the same. d both the mass and the weight of the object will change.

Which situation will produce the greatest change of momentum

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
