Explanation:
A body weighs 160 n on the earth. find its weight on another planet whose mass is 14th the mass of earth and radius 13rd that of the earth.
a.40 n
b.320 n
c.360 n
d.180 nExpress the vector vec a = 5vec i - 2vec j + 5vec k as the sum of two vectors such that one is parallel to the vector vec b = 3vec i + vec k and other is perpendicular to vec b .
a.6vec i - 2vec k, - vec i - 2vec j - 3vec k
b.6vec i + 2vec k, - vec i - 2vec j + 3vec k
c.6vec i + 2vec k, + vec i + 2vec j + 3vec k

The ball has momentum p₁ downwards just before hitting the ground. After rebounding, the ball
leaves the ground with momentum p2 upwards. The ball is in contact with the ground for 0.020 s.
During this time interval, an average resultant force of 25 N acts on the ball.
What is a possible combination of values for p, and p₂?
