A 5 kg rock is thrown at 4 m/s. A 2 kg toy car is traveling at 10 m/s. Which has more momentum?

Formula for momentum: p = mv

p = momentum

m = mass

v = velocity

A 5 kg rock is thrown at 4 m/s.

mass (m) = 5

velocity (v) = 4

Solve for the momentum.

p = 5 * 4

p = 20

A 2 kg toy car is traveling at 10 m/s.

mass (m) = 2

velocity (v) = 10

p = 2 * 10

p = 20

Therefore, both have the same momnetum.

Best of Luck!

Neither has. Their momenta are equal.

Momentum = (mass) • (speed)

Rock: Momentum = (5) • (4) = 20

Car: Momentum = (2) • (10) = 20
