- 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.Professional 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 rocket is fired at a speed of 86.0 m/s from ground level, at an angle of 31.0° above the horizontal. The rocket is fired toward an 7.92- Im high wall, which is located 16.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall? Number i Units
- A rocket is fired at a speed of 83.0 m/s from ground level, at an angle of 45.0° above the horizontal. The rocket is fired toward an 12.5-m high wall, which is located 21.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall? Number i UnitsDock diving is great form of athletic competition for dogs of all shapes and sizes. Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.02 m/s at an angle of 25.0° with respect to the surface of the water. Sheba begins at a height of 0.840 m above the surface of the water. What is her total time of flight up until the instant before she hits the water? Express your answer in seconds.A soccer ball is kicked from the ground with an initial speed of 20.1 m/s at an upward angle of 48.2°. A player 53.9 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s². Number i Unit m/s
- The position of a particle is given by i= (7.7t +7)i- 3tj+5k, where F in (m) and t in (s). The magnitude of the velocity (in m/s) at t= 19.6 s is:On a beautiful spring day, Juan is playing a round of golf. He hits the golfball with an initial velocity of 37 m/s at an angle of 27.4°. If it hits the ground 5.8s later, how far does it travel? Ignore air resistance. Answer: mA fox fleeing from a hunter encounters a 0.770 m tall fence and attempts to jump it. The fox jumps with an initial velocity of 7.30 m/s at an angle of 45.0°, beginning the jump 1.93 m from the fence. By how much does the fox clear the fence? Treat the fox as a particle.
- In an ordinary television set, the electron beam consists of electrons shot horizontally at the television screen with a speed of about 5 x 107 m/s. How far does a typical electron fall as it moves approximately 40 cm from the electron gun to the screen?The highest barrier that a projectile can clear is 18.4 m, when the projectile is launched at an angle of 15.0° above the horizontal. What is the projectile's launch speed?
