We can use the kinematic equation

where Vf is what we are looking for
Vi is 0 since we start from rest
a is acceleration
and d is the distance
we get
(Vf)^2 = (0)^2 + 2*(2)*(500)
(Vf)^2 = 2000
Vf = about 44.721
or 44.7 m/s [if you are rounding this by significant figures]
Answer:
B ) He was the first to systematically study force and motion.
Explanation:
I seen this one before and know the answer since there's 4 options
Answer:
D. Perfectly inelastic
Explanation:
Kinetic energy is lost so the two bodies stick together.
Velocity= 1/4 = 0.25 m/s towards the ball
