dacruick said:That is not true. Think about the situation more thoroughly. You know that his acceleration is 9.8m/s downwards. You also know that his 1.52 metres is achieved at the peak of his jump, at which time his velocity will be 0. So now you 3 pieces of information.
The initial velocity is the speed at which the athlete begins their jump. It is a crucial factor in determining the height the athlete can clear in the high jump event.
The initial velocity is usually measured using a high-speed camera or a laser system. These tools can capture the movement of the athlete and calculate their velocity at the start of the jump.
The initial velocity can be affected by several factors including the speed and technique of the approach run, the height and angle of the athlete's takeoff, and external factors such as wind and surface conditions.
No, the initial velocity is just one of the many factors that contribute to a successful high jump attempt. Other important factors include the athlete's strength, technique, and consistency.
The initial velocity of the 1.52 m high jump record may vary depending on the athlete and the competition. However, it is generally expected to be higher than previous records as athletes continuously improve their techniques and physical abilities.
