Aparticle is projected at an angle of 45 degrees and a velocity of 60 m/s, and taking gravity 9.81 ms, 1. find the equation for the particle for horizontal displacement. 2. find the initial displacement of the vertical motion. 3. find the equation for the particle for vertical displacement. 4. find the time taken to reach the ground. 5. find the horizontal distance that the particle travels. 6. find the maximum height of the particle. 7.find the equation of the trajectory. 8. find the height of the particle when the horizontal distance is 10 m. 9. find the horizontal distance when the height of the particle is 50 m.
that would be because of both gravity and friction. so c
