The topic here is momentum.
When a collision is said to be elastic, it means that the colliding objects now travel at their own new, indivual and distinct velocities, often in different directions.
So we write that as,
(mass of football player x velocity of football player) + (mass of referee x velocity of referee) = (mass of football player x velocity of football player) + (mass of referee x velocity of referee)
(M × 8) + (80 × 0) = (M× 0) + (80 × 5)
8M = 400
M = 50 kg
Answer:
Horizontal component of the initial velocity=v ×cos20°
horizontal displacement= 35m
time taken. (t)=35÷(v×cos20°)
vertical component of the initial velocity= v×sin20°
vertical displacement= -5m(since it is opposite to the direction of the initial velocity. )
application of s=ut+1/2at×t. vertically,
-5=vsin20°×t -1/2 gt×t
-5= vsin20×35/vcos20-1/2×10×35×35/(vcos20×vcos20)
simplify further to obtain v and hence find the time taken
