![]() Convenient and simple to understand, isn’t it? How did I arrive at that conclusion? I made it up. Then we determine the … After that, using the earlier stated….Īnd so, the petal uses a period of 50 hours, 3 minutes and 28 seconds to reach ground. Given that the normal reaction, R, caused by the frictional forces is 60% of the gravitational force acting downwards on the petal, using the formula, F=ma, we can determine the approximate time taken for the petal to reach ground…First, we use the formula…. Using the formula a=(v-u)/t, we can find out the time taken for the petal fall to the ground! First, let me determine the approximate acceleration of the petal. This implies that the acceleration of the petals falling to the ground are actually close to zero, isn’t it? Or does that mean that 5 cms-1 is the final velocity? However, according to the animated movie ‘5 Centimeters Per Second’, cherry blossom petal falls to the ground at a speed of 5 centimeters per second, which is equivalent to 0.18 km/h, which is 0.11 mph, rounded off to the nearest two significant figures. Gravitational acceleration on Earth, provided that there are no other forces acting on the object caused by friction or obscure sources is 9.81 ms-2. Cherry petals travel at the speed of 5 cm/s, true or false? ![]()
