Question

In this question use g = 9.81 m s–1. A particle is projected from a height of 9 m directly above a fixed point O, which is on flat, horizontal ground. The particle’s initial velocity is 20 over 14 ms^-1 (a vector). Find: WITH WORKING OUT PLZ
a- The particle’s maximum height above the ground.
b- The speed of the particle as it hits the ground
c- The direction of motion of the particle when it hits the ground

Answer 1

Answer:

air with an initial speed of 70.0 m/s at an angle of 75.0° 75.0 ° above the horizontal, as ...
