okay u need to use the equation m=Fnet/a. Fnet=540N a=7.74m/s^2 m=540N/7.74m/s^2=69.77kg
Answer:
Value of angle between vector a and b is
.
Explanation:
Vectors a and b have scalar product 6.00
Let
be the angle between a and b.

ab cos
= 6 ...(1)
Vectors a and b have magnitude of vector product 9.00

ab sin
= 9 ...(2)
Dividing equation (2) by (1) we get

tan
= 1.5

= 
Thus, value of angle between vector a and b is
.
The acceleration due to gravity is less at the top of mt. everest because its so far from the center of the earth .
