Chapter-4. Forces and Newton's Laws of Motion 3. A car is towing a boat +27 m/s in a times of 20 mass of the on a trailer. The driver starts from rest and accelerates to a velocity of s. The combined mass of the boat and trailer is 630 kg. The frictional force acting on the trail er is negligible. Find the tension in the hitch that connect the trailer to the car Chapter-5. Dynamics of Uniform Circular Motion 4, A satellite is placed in equatorial orbit above Mars, which has a radius of 3.397 × 106 m and a mass MM = 6.40 x 1023 kg. The mission of the satellite is to observe te Martian climate from an altitude of525 × 105 m. What is the orbital period of the satellite? A) 5.26× 103 s B) 6.38 x 10s s C) 7.47×103 s D) 8.18 x 102 s E) 9.62× 10
