A sled is accelerating down a hill at a rate of 1 m/s2

Question

. If the mass of the sled is suddenly cut in half and the net force on the sled is doubled, what is the acceleration of the sled?

Answer 1

net force=mass*acceleration

so doubling net force doubles acceleration, and cutting mass in half, doubles it again.
Answer: 4 time original acceleration.

Answer 2

4 times original acceleration
