1. A particle is projected with an initial velocity of V m/s and attains a maximum height of 12.5m before landing 100m from the point of projection. Calculate the value of V.
Can someone check my answer for this?
2. The displacement, x, of a particle moving in a straight line is represented by the equation: x = 5cos4t
Find a) The initial velocity of the particle
b) initial acceleration of the particle
initial velocity.. when t = 0, v = 0
when t =0, a = -80
Thanks in advance
