Answer:
8271.92 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Equation of motion
The height reached at 18 seconds is 2916 m
The velocity at 2916 m is 324 m/s
Maximum height reached by the toy rocket is 2916+5355.92 = 8271.92 m
D. Electrons are shared between the bromine atoms and carbon atoms
Answer:
He has 5,609,404 J of potential energy
Explanation:
P.E. = M*G*H
65 * 9.8^2 * 8800
Answer:
A) 1.2
B) 1.1
Explanation:
A)
F = force required to start the box moving = 36.0 N
m = mass of the box = 3 kg
= weight of the box = mg = 3 x 9.8 = 29.4 N
= normal force acting on the box by the floor
normal force acting on the box by the floor is given as
= = 29.4
= Static frictional force = F = 36.0 N
= Coefficient of static friction
Static frictional force is given as
=
36.0 = (29.4)
= 1.2
B)
a = acceleration of the box = 0.54 m/s²
F = force applied = 36.0 N
= kinetic frictional force
= Coefficient of kinetic friction
force equation for the motion of the box is given as
F - = ma
36.0 - = (3) (0.54)
= 34.38 N
Coefficient of kinetic friction is given as
= 1.1
