Question Answered step-by-step 1) What is the acceleration of a car that reaches a speed of three… 1) What is the acceleration of a car that reaches a speed of three meters per second from rest in ten seconds? Use the equation a= (vf-vi)/t in order to solve this question. 2) We know that from our studies on Newton and Galileo’s work that we can calculate the force of gravity acting on objects both on earth and on other planets. Calculate the “weight” or the force of gravity acting on an 80kg person on earth. (Hints: Newton’s second law f=ma is handy here; the acceleration due to gravity on earth is 9.8m/s2 ). What would be the force of gravity acting on the same individual on Mars? Use the equation of Universal gravitation F= ( m1 x m2 x G)/d2The mass of Mars is 6.4171×1023 kg and its radius is 3396.2 kgG= 6.67 x 10-11 N-m2/kg Science Physics BUSINESS INX100 Share QuestionEmailCopy link Comments (0)
