Could I have help with this physics question?

The figure depicts the sum of two velocities, vA and vB. The magnitude of the sum is 5.5 m/s and the angles shown in the image are θ1 = 26.3°, and θ2 = 16.1°. 1. Find the magnitude of velocity vA in meters per second.  2. Find the magnitude of velocity vB in meters per second.

We know that the moon Callisto revolves around Jupiter during a period of 17.0 days.17.0 days. The average distance from the center of Jupiter to the center of Callisto is 1.95×109 m.1.95×109 m. What is the acceleration ?a of Callisto due to its motion around Jupiter?

In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). V. o h d The top of a pool table is a height h = 3.25 ft from the floor. If a player's ball lands a distance d 14.75 ft from the table edge, what is her break shot speed vo? 12.3 Vo = mph Incorrect At what speed v did her pool ball hit the ground? 4.21 mph = Incorrect

When there is no air resistance what best describes the vectors of a projectile in motion:   a.The acceleration vector and velocity vector are both constant magnitude.   b.The acceleration vector is constant magnitude and perpendicular to the trajectory. The velocity vector is at a tangent to the trajectory   c.The acceleration vector is constant and points straight down. The velocity vector is perpendicular to the trajectory   d.The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory
