AP Physics ~ A good jump in the long jump event is

Silverbolt · Sep 17, 2012

A good jump in the long jump event is 3.7m. If the jumper leaves the ground at an angle of 25°, what speed must he need to jump the 3.70m distance?

→Could you use this equation: vf²=vi²+2aY aka (final velocity)²= (initial velocity)²+2(acceleration)(distance in the y-direction)
→So, that would be: 0=(vsin25 °)²+2(-9.8)(3.7)∴ v=13.1m/s

Please help me if I am wrong.

It is in x direction(long jump) not y direction(high jump)

You can't use the formula which you have used.
In the projectile motion, the time of flight can be found by using vertical component of the velocity and the range can be found by using horizontal component of the velocity. Now try to solve the problem.

What is the long jump event in AP Physics?

The long jump event in AP Physics is a track and field event that measures the horizontal distance an athlete can jump from a standing position. It is a combination of speed, strength, and technique.

What is considered a good jump in the long jump event?

A good jump in the long jump event is typically determined by the distance the athlete can jump. In AP Physics, a good jump is considered to be one that maximizes the athlete's velocity and angle of takeoff to achieve the furthest horizontal distance possible.

What factors affect a good jump in the long jump event?

Several factors can affect a good jump in the long jump event, including the athlete's speed, strength, takeoff angle, and technique. The runway surface, wind conditions, and equipment can also impact the jump.

How does physics play a role in the long jump event?

Physics plays a significant role in the long jump event. The principles of force, velocity, and acceleration are essential for the athlete to achieve a longer jump. The athlete's center of mass, takeoff angle, and air resistance also involve physics concepts.

What techniques can help improve a jump in the long jump event?
