Influenced by the gravitational pull of a distant star, the velocity of an asteroid changes from from +19.7 km/s to −17.4 km/s over a period of 2.12 years. What is the total change in the asteroid's velocity? (Indicate the direction with the sign of your answer.) What is the asteroid's average acceleration during this interval? (Indicate the direction with the sign of your answer.)

Influenced by the gravitational pull of a distant star, the velocity of an asteroid changes from from +19.2 km/s to -19.3 km/s over a period of 1.90 years. (a) What is the total change in the asteroid's velocity? (Indicate the direction with the sign of your answer.) The change is the final velocity minus initial velocity. Also, watch unit conversions. m/s (b) What is the asteroid's average acceleration during this interval? (Indicate the direction with the sign of your answer.)...

Over a time interval of 1.99 years, the velocity of a planet orbiting a distant star reverses direction, changing from +20.7 km/s to -22.0 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s2) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration.

Over a time interval of 1.61 years, the velocity of a planet orbiting a distant star reverses direction, changing from +20.1 km/s to -20.7 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s2) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration.

(a) An asteroid is in an elliptical orbit around a distant star. At its closest approach, the asteroid is 0.700 AU from the star and has a speed of 54.0 km/s. When the asteroid is at its farthest distance from the star of 36.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 x 101 m. You may assume that other planets and smaller objects...

A particle is executing circular motion. The velocity of the particle changes from zero to (0.3i+0.4j) m/s in a period of 1 second. The magnitude of average tangential acceleration is: A. 0.1 m/s/s B. 0.2 m/s/s C. 0.3 m/s/s D. 0.5 m/s/s I know the answer is D, but how is this problem solved? What is "i" and "j" ?

A 51.0g Super Bal traveling at 28.5 m/'s bounces off a brick wall and rebounds at 19.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.45 ms, what is the magnitude of the average acceleration of the ball during this time interval? 10700 Average acceleration is the change in velocity divided by the time interval. m/s Need Help? hud Yaehs A position-time graph for a particle moving along the x axis...

9) Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 71.3 N , Jill pulls with 94.1 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 143 N . (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. magnitude of...
