A) Metal expand upon heating. B) Alloys expand less upon heating than elemental metals. C) Alloys expand more upon heating than elementals metals. D) The rate of the expansion of metals is directly proportion to the temperature to which it is heated
When it is not moving or on the ground
The impulse is equal to the variation of momentum of the object:
where m is the mass object and
is the variation of velocity of the object.
The ball starts from rest so its initial velocity is zero:
. So we can rewrite the formula as
or
and since we know the impulse given to the ball (I=16 Ns) and its mass (m=2 kg), we can find the final velocity of the ball:
U = m * g * h
350 = 17 * 9.8 * h
h = 350 / 166.6
h = 2.10
Nearest whole number = 2.00
In short, Your Answer would be 2 meter
Hope this helps!
