Question

Three Kids pull on a toy. Kim pulls with a force of 30N north, jim pulls with a force of 30 N south, and Tim pulls with a force of 15 N. The acceleration of the is 15 m/s^2 33 m/s^2 10 m/s^2 need more information A tow truck exerts a force of 3000 N on a car. which then accelerates at 2 m/s^2 What is the mass of the car 500 kg 1500 kg 1000 kg 3000 kg none of these The force exerted on the tires of a car that directly accelerate it along a road is exerted by the road. engine. Tires. air. none of the above A rock weighs 30 N on Earth and another rock weighs 30 N on the Moon. Which rock has the greater mass? They have the same mass. B) the one on Earth the one on the Moon not enough information As water drops fall at a steady rate from a leaking faucet they remain at a relatively fixed distance from one another. get closer together. get farther apart. A satellite is in orbit around the earth. Which one feels the greater force? The satellite because the earth is so much more massive The earth because the satellite has so little mass Earth and the satellite feel exactly the same force. It depends on the distance of the satellite from Earth. You are in a train traveling on a horizontal track and notice that a piece of luggage starts to slide directly toward the front of the train. From this observation, you can conclude that this train is speeding up slowing down. changing direction. speeding up and changing direction. slowing down and changing direction.

Explanation / Answer

Question 16). mass is required for acceleration, since acceleration a= F/m, therefore the answer is D

NEED MORE INFERMATION THAT IS MASS

Question 17) Force = mass x acceleation

mass = F/a = 3000/2 = 1500m/s2

   Answer is B

Question 18.) By the road due friction on the tyres. Answer is A

Question 19) The mass on the earth m = 30/g = 30/10 = 3kg

The mass on the moon is m' = 30/(10/6) = 18kg

Hence the mass on moon is more. Answer is C
