A particle moving at a velocity of 2.3 m in the positive x direction is given an acceleration of 4.9 m/s^2 in the positive y direction for 4.3s. What is the speed of the particle? Answer in units of m/s.
Thank you for the opportunity to help you with your question!
velocity in Y direction = 4.9 * 4.3 = 21.07 m/S
velocity in x direction = 2.3 m/s
final velocity = square root ( 2.3^2 + 21.07^2) = 21.19 m/s
