A force of 75 N is exerted on a student riding a skateboard. The total mass of the student and the skateboard is 50 kg. Choose the equation below that would result in the rate the student and her skateboard would accelerate to the nearest m/s².

• 75 N - 50 kg

• 50 kg ÷ 75 N

• 75 N ÷ 50 kg

• 75 N + 50 kg
