A Tesla Model 3 electric car can accelerate from rest to a speed of 27.0 m/s (about 60 mph) in 2.30 seconds. Let's say such a car does that, but then travels linearly thereafter at constant velocity for a distance of 8.00 km. whereupon it then slows down uniformly at a rate of 2.00 m/s2, until it is completely stopped. About how many times Earth's acceleration due to gravity is the magnitude of the acceleration of the Tesla? (A) 0.60 times (B) 1.2 times (C) 2.8 times (D) 7.5 times (E) 12 times How far did the Tesla travel during the first 2.3 seconds of its trip (note 1.0 m = 3.3 feet)? (A) 14.3 feet (B) 31.1 feet (C) 74.2 feet (D) 102. feet What is the total distance travelled by the Tesla during this trip? (A) 8.21 x 10¹ m (B) 8.21 x 10²m (C) 8.21 x 10³ m (D) 8.21 x 10¹ m (E) 8.21 x 10³ m A potato is launched vertically upward with a velocity of +40.0 m/s from the edge of a cliff that is 50.0 m tall. Assume the potato leaves from the very edge of the cliff so it passes the cliff edge and falls to the ground of the nearby valley below. Answer each of the following neglecting air resistance. Approximately how long is the potato airborne? (A) 5.1 sec (B) 7.9 sec (C) 8.33 sec (E) 14.7 sec below the cliff? (D) 9.26 sec What is the approximate impact velocity of the potato the moment it strikes the ground (A) -9.81 m/sec (B)-26.4 m/sec (C) -33.5 m/sec (D) -42.7 m/sec What is the maximum height above the ground below the cliff reached by the potato? (A) 8.16 x 10¹ m (B) 1.32 x 10² m (C) 6.41 x 10²m (D) 9.47 x 10² m (E) 540. feet. (E) -50.8 m/sec (E) 1.32 x 10³ m
