- > On level ground a shell is fired with an initial velocity of 39.0 m/s at 62.0° above the horizontal and feels no appreciable air resistance. Part B How long does it take the shell to reach its highest point? Express your answer using three significant figures. t = 3.51 s Submit Part C Correct Find its maximum height above the ground. Express your answer using three significant figures. hmax = Previous Answers Submit Part D HA Value Request Answer Units How far from its firing point does the shell land? P Pearson ?B9I drive a Nissan Leaf to work. With the e-pedal on, the motor recovers energy through braking very aggressively. I need about 7 KW-hour to come to school if I use mostly the freeways. That’s about 5 KW-hour if I take mostly local streets. From the energy perspective, can you offer an explanation to explain this difference?
- 6. In the skateboarder scenario below, a Determine the skater's vertical displacement during the jump? b) To the nearest hundredth of a second, determine how long was the skateboarder in the air? A skateboarder rolls horizontally off the top of a staircase at a speed of m 14.5 m/s and lands at bottom of the stairs. The staircase has a horizontal length of 8.00 m. We can ignore air resistance.1 Standing on the roof of a 74-m tall building, a girl holds her hand past the edge and throws a ball straight up at 9.8 m/s. The ball rises, then falls and strikes the ground. Considering "up" to be the positive direction, find the ball's velocity v when it is 45 m above the ground. Remember to include a "-" sign if the velocity is negative.
