Hello everyone! I am having a little trouble with my physics homework and am hoping for someone(s) to confirm if I am on the right track. Please and thank you! 1. In a total time of 2.0min, a duck on a pond paddles 22m [36° N of E] and then paddles another 65m [25° E of S]. Determine the duck's i) total distance travelled Total = 22m + 65m = 87m ii) average speed v = d/t = 87m/120s = 0.73m/s iii) total displacement a² = b² + c² 65² = 22² +c² c = 61 iv) average velocity v = d/t = 65-22/120 = 0.36m/s[E] 2. The skid marks of a car was 150m from the point where the driver applied the brakes to where the car came to rest. The driver was travelling at 80km/h(22m/s) when the brakes were applied. Calculate the acceleration of the vehicle. Vf² = Vi² + 2aΔd 0 = (22m/s)² + 2a(150m) 484/150 = 2a a = 1.6m/s² 3. An archer shoots an arrow straight up into the air with an initial velocity of 45m/s . Calculate the maximum height of the arrow. Vf² = Vi² + 2aΔd 0 = (45m/s)² + 2(-9.8m/s²) Δd Δd = -2025/-19.6 Δd = 103m Thank you once again!!
