A marching band player walks directly north at a speed of 2.50 m/s for a time of 12.0 seconds, turns 35.0°to the east and walks at half that speed for another 15.0 seconds. What is the players total displacement and average velocity for the entire trip?
A cart is moving horizontally along a straight line with constant speed 30 m/s.
Problem 12:A cart is moving horizontally along a straight line with constant speed 30 m/s. A projectile is to be fired from the moving cart in such a way that it will return to the cart after the cart has moved 80m. At what speed (relative to the cart) and at what angle (to the horizontal) must the projectile be fired?NOTE: remember that to calculate the speed of the projectile respect to the cart, we need to subtract the velocity...

A horse canters away from its trainer in a straight line, moving 37 m away in 9.1 s . It then turns abruptly and gallops halfway back in 1.8 s . Calculate its average speed for the entire trip. Express your answer using two significant figures. Calculate its average velocity for the entire trip, using "away from the trainer" as the positive direction. Express your answer using two significant figures.
