Question

The height y and horizontal distance x covered by a projectile in a time t seconds are given by the equationd y=8t-5t^2 and x=6t. if x and y are measured in metres
The acceleration due to gravity is

Answer 1

Answer:

y direction ma acceleration =d^y/dt^2

=-10 =a1

x direction ma acceleration =d^2x/dt^2

=0 =a2

a=(a1^2+a2^2)

=10
