- Recently a space x launch vehicle was coasting at a constant velocity of 15m/s in the + y direction relative to a space station . The pilot of the vehicle fired a special RCS thruster which causes it to accelerate at 8m/s^2 in the +x direction . After 9.1 s the pilot shuts off the RCS thruster . After RCS thruster is turned off find the magnitude of the vehicles velocity in +x direction.A track meet is held on a planet in a distant solar system. A shot-putter releases a shot at a point 2.0 m above ground level. A stroboscopic plot of the position of the shot is shown in the figure, where the readings are 0.76 s apart and the shot is released at time t = 0. (a) What is the initial velocity of the shot in unit-vector notation? (b) What is the magnitude of the free-fall acceleration on the planet? (c) How long after it is released does the shot reach the ground? (d) If an identical throw of the shot is made on the surface of Earth, how long after it is released does it reach the ground? y (m) 10 5 0 t=0 90 5 10 15 x (m) 20 20 25 30Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?
- A boat that can travel at 2.50 m/s in still water is heading directly across a river that is flowing at a rate of 1.25 m/s, i.e., so that it will end up downstream. (a) What is the velocity of the boat as measured by a person standing on the shore? Give both the magnitude and the angle. (b) If the river is 175 m across, how long does it take the boat to cross the river and in this time how far down stream will the boat have traveled? (c) Provide a diagram of the situation.Johnny comes across a river that is 252 meters wide. He sees that the water flows eastward with a uniform velocity of 1.10m/s. Johnny sees his friend Sarah start her boat at point A on the south bank and start to cross the river to point B which is on the other side. Suppose the trip takes 3 minutes. Figure out the velocity of sarah's boat with respect to a) Johnny who is stationary on the ground b) A floating goose that's moving with the water. N B W-E S Vriver = 1.1 m/s A 252 mA river is about 5.7 m wide. Suppose an athlete wants to jump “over the river” and leaps at an angle of 35o with respect to the horizontal. What is the minimal initial speed that would allow the athlete to clear the gap? How much time is the athlete in the air? (please include images to help me understand :))
- two cars start 220 m apart and drive toward each other at a steady 10.0 m/ s. On the front of one of them, an energetic grasshopper jumps back and forth between the cars with a constant horizontal velocity of 15.0 m/s relative to the ground. The insect jumps in the instant he lands, so he spends no time resting on either car. what total distance does the grasshopper travel before the car hits?The black market sold Einstein a gun that is able to launch clumps of cookie dough. By accident einstein launches two clumps of cookie dough back to back vertically into the air. Launch speed was equivalent to 40m/s and time between launches = 5.5s. The cookie doughs collide and clump into 1 massive clump in the air and come back and clogg the gun. At what speed does the big clump enter the gun assuming both clumps were in mass. %3DIf you fire a projectile at various speeds, does this change the time that the projectile is in the air? Explain why or why not?
