Kinetic Energy is defined by Ke=1/2mv^2. Plug in and solve for v.
2,000 = 1/2(1000)(v)^2
4=(v)^2
v=2 m/s
The car must move at 2 m/s to have a Ke of 2,000 Joules.
Helpful ways: braking - it makes the wheels slow down faster, friction from the chain
harmful: when you fall and slide across the ground, when you get your leg stuck in the chain
You could use clay, sticks, rocks, Legos,
