- 7) A ball is thrown in the air at an angle of 40°. If the maximum height it reaches is 10 m, what must be its initial speed? a) 17.46 m/s b) 21.78 m/s c) 304.92 m/s d) 474.37 m/sA 3kg ball is thrown straight into the air at 8m/s. How high does it travel? Use g=9.8m/s2The velocity of a particle is given by v = 29t²-88t - 196, where v is in feet per second and t is in seconds. Plot the velocity v and acceleration a versus time for the first 4 seconds of motion. After you have the plots, answer the questions as a check on your work. -1 Questions: + 0 + 1 When t = 0.5 sec, V = 2 i When t = 3.3 sec, V = i + 3 +s, ft or m When the acceleration is zero, the velocity is i ft/sec, a = ft/sec, a = i i ft/sec. ft/sec² ft/sec²
- 3. Bob (52.0kg) was curious about the amount of air resistance (friction) that would act on him as he fell through the air, so he conducted an experiment. He stepped out of a third story window, 15.0m above the ground, and measured that it took 1.94s to hit the ground (don't worry, there was a soft mat to cushion the impact). Assuming his initial velocity was zero as he stepped out of the window, determine the force of air friction that acted on Bob as he fell.A car brakes with a constant acceleration. If the car's speed is tripled, the time to come and the stopping distance changes by a factor of to a stop changes by a factor of 0 9,3 O 9, 9 O 1,1 (unchanged) O 3, 9A rifle with a muzzle velocity of Vo shoots a bullet at a target R away at the level of the muzzle. How high above the target must the rifle be aimed so that the bullet will hit the target? (Neglect air resistance.) Let Vo = 250 m/s and R = 100 m. Find H
