A boat which heads straight across a 100-meter wide river with a speed of 8 m/s (relative to the water). The river water flows south at a speed of 3 m/s (relative to the shore). Which of the following changes would cause the boat to reach the opposite shore in more time? The river is 80 m wide The boat heads across the river at 10 m/s The river flows south at 2 m/s iv. The boat changes it's heading to an angle of 45° v. None of the above A car traveling with an initial velocity of vapplies its brakes, and comes to a stop after x meters. Assuming that the car's deceleration due to the brakes is constant, what would be the stopping distance if the car was initially travelling at a velocity of 30'? A. % x meters B. x meters C. 3x meters D. 9x meters E. 18x meters A bullet is fired into the air at an angle of 30" below the horizontal. At the same time and from the same height, a bullet is dropped. If we neglect the effects of air resistance, how will the time the two bullets spend in the air compare ? A. the bullet that is fired will spend longer in the air, hitting the ground after the dropped bullet B. the bullet that is fired will spend less time in the air, hitting the ground first C. the bullet that is fired will spend less time in the air, hitting the ground after the dropped bullet D. the bullet that is fired will spend longer in the air, hitting the ground first E. both bullets will spend the same amount of time in the air, hitting at the same time.
