PLEASE HELP! This is a math/science question, I will mark brainliest show your work

(use the GUESSU method)

Question 1: What is the mass of an object if a force of 17 N causes it to accelerate at 1.5 m/s/s? Ignore friction.

Question 2: It takes 8.3 seconds for Mei to run 50 meters. What is their average speed in m/s?

Question 3: Tarek is planning to backpack in Tahoe. If his average speed is 4 mi/hr how many hours will it take him to hike 15 mi.

Question 4: Mr. Mike is on his bike traveling at an average speed of 10 miles per hour for 0.75 hours. What distance does he travel?

Question 5: A tennis ball, when served by Sunni, goes from 0 m/sec to 80 m/sec in 1.5 sec. What is the acceleration of the ball in m/s2?

Question 6: Ada is running with an initial velocity of 2.0 m/s and accelerates at a constant rate of 1.2 m/s2 for a time of 2 seconds. What is her final velocity at the end of this time?

Question 7: Kwame is measuring the speed of a marble in freefall, so the acceleration due to gravity is 9.8m/s/s (ignore air friction). At 0 seconds the marble is going 0 m/s. The marble goes through a sensor which shows the final speed as 28 m/s. How long did it take for the marble to fall to the sensor?

Please try to do this in two hours.
