weight = mg
W on earth = 800N
mg = 800 N
m(9.8 m/s²)= 800N
dividing 9.8 both sides
m=800/9.8 ( as g=9.8m/s² on earth)
m=81.63 kg
Now weight on Mars
w=mg
=(81.63kg) ×(3.76m/s²)
w=306N
Using kinematic equation s=ut + 1/2 at^2(u = initial velocity=0, s=120m, t= 6.32s), 120 = 0(t) + 1/2 a(6.32)^2. a = 120x2/(6.32)^2 = 6m/s^2.

Answer:
Mass of receiver is 92 kg
Explanation:
We have given mass of tackler
Let the mass of receiver is
When tackler moving alone velocity is m/sec
And when tackler and receiver is together velocity is = 2.5 m/sec
So from conservation of momentum
So mass of receiver is 92 kg
