Question

In 1993, Wayne Brian threw a spear a record distance of 201.24 m.(This is not an official sport record because a special device was used to "eloa gate" Brian's hand.) Suppose Brian threw the spear at a 35.0° angle with respect to the horizontal. What was the initial speed of the spear?

Answer 1

The student's question is about calculating the initial speed (velocity) of a spear thrown at a 35.0° angle using the principles of projectile motion in Physics, which involves applying kinematic equations and the range formula for projectile motion.

Step-by-step explanation:

The question pertains to the calculation of the initial speed (velocity) of a spear thrown at a particular angle, utilizing the principles of projectile motion from the field of Physics. To find the initial speed of the spear thrown by Wayne Brian at a 35.0° angle, we need to use the kinematic equations for projectile motion. These equations consider the acceleration due to gravity and the horizontal and vertical components of the initial velocity. Although the exact calculation isn't provided, the process involves breaking down the initial velocity into horizontal and vertical components using trigonometry, applying the range formula for projectile motion, and incorporating the given distance and angle to solve for the initial speed.
