33. ll A gray kangaroo can bound across a flat stretch of ground B0 with each jump carrying it 10 m from the takeoff point. If the kangaroo leaves the ground at a 20 angle, what are its (a) take- S off speed and (b) horizontal speed?
Solution
here,
theta = 20 degree
a)
let the take off speed be u
the horizontal range ,R = 10 m
R = u^2 * sin(2*theta)/g
10 = u^2 * sin(2 * 20) /9.81
solving for u
u = 12.4 m/s
b)
the hoeizontal speed , ux = u * cos(theta)
ux = 12.4 * cos(20) m/s
ux = 11.6 m/s
