Start with the equation:
Rearrange the equation for time to get:
Distance = 300
speed = 20
Insert into the new equation:
15 seconds is your answer
The gravity on the moon is different than on earth.
Answer:
x = 10.53 m
Explanation:
Let's analyze this problem a bit, the time that the cowboy must take to fall must be the time that the horse takes to arrive
Let's start by looking for the cowboy's time, which starts from rest and the point where the chair is is y = 0
y =y₀ + v₀ t - ½ g t²
0 = y₀ - ½ g t²
t =
we calculate
t = √(2 3.22 / 9.8)
t = 0.81 s
the horse goes at a constant speed
x = t
x = 13 0.81
x = 10.53 m
this is the distance where the horse should be when in cowboy it is left Cartesian
Answer:
c.they have opposite charges.
Explanation:
because the protons have a positive charge and the neutrons have no charge.
Answer
given,
constant net force = 75 N
distance = 0.60 m
mass = 0.20 Kg
a) by work energy theorem work done is equal to change in kinetic energy.
initial speed = 0 m/s
b) We know.
v² = 450
v = 21.21 m/s
the final speed of the object is equal to v = 21.21 m/s
