MGA SAGOT NI ASHE MONTAGE (SUBUKAN NIYONG IBENTA SOURCE KO SS KAYO SAKIN!) Calculate (0.82 + 0.042) × (4.49 × 10 3 ), keeping only significant figures. a. 3870 A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 68.6 m/s in 7.00 seconds. She then pulls the parachute cord and after a 4.00-second constant deceleration, descends at 9.0 m/s for 60.0 seconds, reaching the ground. From what height did the parachutist jump? a. 935 m A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 58.8 m/s in 6.00 seconds. She then pulls the parachute cord and after a 4.00-second constant deceleration, descends at 10.0 m/s for 80.0 seconds, reaching the ground. From what height did the parachutist jump? c. 1110 m A steel sphere of mass M has a large spherical cavity inside. A second solid steel sphere has mass 4 M , but has the same outer radius as the first sphere. If the terminal velocity of the first sphere is v , what would be the terminal velocity of the second sphere? Select one: 2 v. Which one of the choices below represents the preferred practice regarding significant figures when multiplying the following: ? c. 195.72 A runner circles a track of radius 100 m one time in 100 s at a constant rate. The greatest change in his velocity from his starting velocity: b. occurs one-half of the way around the track. An automobile of mass 2000 kg moving at 20 m/s is braked suddenly with a constant braking force of 10,000 N. How far does the car travel before stopping? a. 40 m The highest mountain on Mars is Olympus Mons, rising 22 000 meters above the Martian surface. If we were to throw an object horizontally off the mountain top, how long would it take to reach the surface? (Ignore atmospheric drag forces and use g Mars = 3.72 m/s 2 .) c. 1.8 minutes
