The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due its motion. It is given by
where
m is the mass of the object
v is its speed
For the car in this problem, we have:
m = 1000 kg is its mass
v = 30 m/s is its speed
Substituting into the equation, we find the kinetic energy of the car:

Answer:
200 N
Explanation:
Applying,
The force a golie must exert on the ball is,
F = ma...................... Equation 1
Where m = mass of the ball, a = acceleration of the ball.
But,
a = Δv/t............... Equation 2
Where Δv = change in velocity, t = time.
Substitute equation 2 into equation 1
F = m(Δv/t)............... Equation 3
From the question,
Given: m = 0.8 g, t = 0.1 s, Δv = 25 m/s
Substitute these values into equation 3
F = 0.8×25/0.1
F = 200 N
