Explanation:
The kinematic relations allow finding that the answers for the velocity and the position of the car in a time of 2 s. are:
- The velocity is v = 7 m / s
Kinematics studies the movement of bodies giving relationships between the position, velocity and acceleration of the body
They indicate that the initial velocity is v₀ = 1 m/s, that the car has an acceleration of a = 3 m/s² and asks about the position and velocity after a time of t = 2s
Let's used the kinematics relation
v = v₀ + a t
v = 1 + 3 2
v = 7 m / s
We look for the position
x = v₀ t + ½ a t²
x = 1 2 + ½ 3 2²
x = 8m
In conclusion, using the kinematics relations we can find the answers for the speed and the position of the car in a time of 2 S. They are
- The velocity is v = 7 m / s

Answer:
the work function of the metal is 4.167 x 10⁻¹⁹ J .
Explanation:
Given;
wavelength of the incident light, λ = 450 nm = 450 x 10⁻⁹ m
kinetic energy, K.E = 2.5 x 10⁻²⁰ J
The energy of the incident light is calculated as;
Apply Einstein photoelectric equation to determine the work function of the metal;
E = W + K.E
where;
W is the work function of the metal
W = E - K.E
W = 4.417 x 10⁻¹⁹ J - 2.5 x 10⁻²⁰ J
W = 44.17 x 10⁻²⁰ J - 2.5 x 10⁻²⁰ J
W = 41.67 x 10⁻²⁰ J
W = 4.167 x 10⁻¹⁹ J
Therefore, the work function of the metal is 4.167 x 10⁻¹⁹ J .
