Question

A. What is the balls velocity at t=3 a. Provide x and you components of velocities and the magnitude. B. What is the balls at t=2 s. Provide x and y components. A. What is the balls velocity at t=3 a. Provide x and you components of velocities and the magnitude. B. What is the balls at t=2 s. Provide x and y components. B. What is the balls at t=2 s. Provide x and y components. A physics on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in the figure belo. the ball's position is shown at 1. 0s intervals until t = 3. 0s, At t = 1. 0s the ball's velocity has components vx = 2. 0m/s, vy = 3. 0 m/s. What is the ball s velocity at t = 3s. Please provide x and y components of velocities and the magnitude. What is the ball's velocity at t = 2s. Please provide x and y components of velocities and the magnitude.

Explanation / Answer

The ball is at its max height at t=2. So, it has same velocity magnitude at t=1 and t=3.

a. At, t=3, Vx=2 m/s and Vy= 3m/s downward

b. At , t=2, Vx= 2m/s and Vy= 0m/s

c. In trajectory 1-2

Vy= Uy-at

0= 3-a*1

a= 3 m/s2

d. Here Vy at t=0 iss 6m/s

H= ut-at2/2

   6*2-3*4/2

=12-6= 6m
