A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?

A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.

A projectile is launched with an initial speed of 52.0 m/s at an angle of 32.0° above the horizontal. The projectile lands on a hillside 3.50 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) (a) What is the projectile's velocity at the highest point of its trajectory? 27.55 x magnitude Your response differs from the correct answer by more than 10%. Double check your calculations. m/s 44.09...
