Find the mass of a football player who weighs 1250 n.

1 answer:

7 0

We know, W = m * g
1250 = m * 9.8
m = 1250 / 9.8
m = 127.55 KG

In short, Your Answer would be 127.55 Kg

Hope this helps!

A boat having stones floats in water. If stones are unloaded in water, what will happen to the level of water?

Pani-rosa [81]

Explanation:

If the stones are unloaded from the boat, the weight of the boat will decrease. Therefore, the volume of the water displaced by the boat will also decrease. Due to this, the volume of the boat immersed in the water decreases. Hence, the level of the water around the boat will decrease.

horizontal analysis

d = (vx₀)t

t = d/vx₀

horizontal analysis

0 = vy₀t + ½gt²

0 = vy₀(d/vx₀)+ ½g(d/vx₀)²

as vy₀ = v₀sin45 and vx₀ = v₀cos45 and are equal.

0 = d + ½g(d²/v₀²cos²45)

-d = ½g(d²/v₀²cos²45)

-dv₀² = ½g(d²/cos²45)

v₀² = -½g(d/cos²45)

v₀² = -½(-9.81(32.0/cos²45)

v₀² = 313.92

v₀ = 17.717787...

v₀ = 17.7 m/s
