The best and the most correct answer among the choices provided by the question is the first choice. When he lands on Mars, his mass will be equal to 75 kilograms, but his weight might be lesser when he is in Mars. I hope my answer has come to your help. God bless and have a nice day ahead!

Answer from: rntaran2002

For 1: the correct answer is Option A.

For 2: The correct answer is Option C.

Explanation: There is a huge difference in mass and weight.

Weight is defined as the force which is exerted on the body by gravity. This term is not a constant term. It is dependent on the value of of acceleration due to gravity. Unit for this term is Newtons. Formula used to calculate weight is:

W = mg

Mass is defined as the actual matter which a body contains. This term remains constant at every point on the universe. Unit for this term is kilograms.

In the given question, it is given that the gravitational pull of Mars is less than the Earth which means that the value of 'g' is less for Mars. As, weight is directly proportional to the value of 'g', so the weight will be less on Mars than on Earth.

Mass remains constant.

Hence, the correct option for 1 will be Option A and that for 2 will be Option C.

Answer from: Quest

Answer: it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.explanation: we have equation of motion $s=ut+\frac{1}{2} at^2$ ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/s $s=0*t+\frac{1}{2} *2.18*t^2$ $s=1.09t^2[/ 2equating equation 1 and 2 [tex]4.75t = 1.09t^2\\ \\ t=4.36 seconds.$ so it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.
