Problem One. A daredevil on a motorcycle leaves the end of a ramp with a speed of 25.0 m/s. If his speed is 18.0 m/s when he reaches the peak of the path, find the maximum height he reaches in meters. (Ignore friction and air resistance.) h (A) 25.0 (D) 15.4 (В) 36.7 (E) 17.3 1.) (C) 29.3 If the mass of the motorcycle and rider together is 300 kg, find the work done by gravity (in kJ) at the moment he is at the peak of the path. 2.) (A) – 28.7 (В) — 38.5 (С) — 45.3 (D) – 34.3 (E) – 22.7 Determine his speed (in m/s) when he is half-way to the top of his peak height. 3.) (A) 24.7 (В) 21.8 (C) 57.4 (D) 39.7 (E) 31.2
