Please help with both questionsplease!!
Initially, a particle is moving at 5.10 m/s at an angle of 35.0° above the horizontal(+x axis). Two seconds later, its velocity is 5.24 m/s at an angle of 50.0° below thehorizontal. What was the particle's average acceleration duringthis time interval?
1 m/s2 (x component)
2 m/s2 (ycomponent) Please help with both questionsplease!!

Explanation / Answer

Initial velocity in x - direction v = 5.1 cos 35 = 4.177m / s Final velocity in x-direction v ' = 5.24 cos 50 = 3.368m / s time t = 2 s X-component of Accleration a = ( v ' - v ) / t                                                = -0.404 m / s ^ 2 Initial velocity in y - direction v = 5.1 sin35 = 2.925 m / s Final velocity in y-direction v ' = -5.24 sin 50= -4.014 m / s time t = 2 s X-component of Accleration a = ( v ' - v ) / t                                                = -3.46 m / s ^ 2 Initial velocity in y - direction v = 5.1 sin35 = 2.925 m / s Final velocity in y-direction v ' = -5.24 sin 50= -4.014 m / s time t = 2 s X-component of Accleration a = ( v ' - v ) / t                                                = -3.46 m / s ^ 2
