- A high-powered spring cannon discharges its ball at 16.6 m/s. If the cannon is fired at an elevation of 77 degrees, what is the maximum height reached by the ball? 13 m 14 m 15 m 16 mA daredevil tries to jump a canyon of width 10 m. To do so, he drives his motorcycle up an indine sloped at an angle of 15 degrees. What minimum speed is necessary to clear the canyon? -10m 15 degreesA skater with mass 66 kg is skating on a horizontal surface at a constant speed 4.2 m/s. There is a ramp ahead, and the skater has just enough speed to make it to the top of the ramp (meaning the speed at the top of the ramp is 0 m/s). What is the height of the ramp in the unit of meters? Use g = 10 m/s2 for the acceleration due to gravity.
- Trying to escape his pursuers, a secret agent skis off a slope inclined at 30° below the horizontal at 60 km/h. To survive and land on the snow 100 m below, he must clear a gorge 60 m wide. Does he make it? Ignore air resistance.The acceleration due to gravity on the surface of Mars is reported as 3.7 m/s2. Express this value in terms of km/min2.In MAY 26, 2021, Greece's long jump champion Miltiadis "Miltos" Tentoglou achieved a distance of 8.60 meters in the long jump, the best jump in the world for 2021, at a track and field event in Athens.
