A bus driver heads south with a steady speed of v1=20.0 m/s for t1=3.00 min, then makes a right turn and travels at v2=25.0 m/s for t2=2.60 min, and then drives northwest at v3=30.0 m/s for t3=1.00 min For this 6.60-min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.) (b) average speed (in m/s) (c) average velocity (Enter the magnitude in m/s and...
A 2-kg ball is thrown up vertically from the ground with initial speed of 9.8 m/s. When it lands on the ground, it is deflected 10 m East from the launching position due to drag by wind toward East. What is the magnitude of the drag? Ignore drag in the vertical direction. This is Question Verbatim. The only hint we were given is that the 10m deflection is extremely important to solving this. I have no idea where to start...
You throw a ball upward with an initial speed of 3.0 m/s from an initial height of 1.5 m. After you throw the ball, its acceleration is 9.81 m/s2 downward. Taking upward to be the positive direction, write the position-time equation for the ball's motion. Express your answer in terms of t. t is expressed in seconds.

1. A 0.25 km wide river has a uniform flow speed of 4.2 m/s toward the east. It takes 23 s for a boat departing from the south bank to travel straight across the river to a position directly north of its departure. a) In what direction must the boat be pointed so as to accomplish this? Express your final answer relative to the North direction. (Hint: Start by drawing a right triangle representing the vector addition)...

Sketch the three vectors c Patricia is walking at 3 m/s such that the x component of her velocity is 1 m/s. Write her velocity in component form. What is its angle? (There are two possible solutions. Find both.) A helicopter flies upwards at a speed of 6.0...
Use the approximation that v→avg≈p→f/m for each time step. You throw a metal block of mass 0.34 kg into the air, and it leaves your hand at time t= 0 at location <0, 2, 0> m with velocity <4.5, 3.5, 0> m/s. At this low velocity air resistance is negligible. Using the iterative method shown in Section 2.4 with a time step of 0.05 s, calculate step by step the position and velocity of the block at t= 0.05 s,...

1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...
