Answer: Force = Mass X Acceleration
F = 5 x 2
F = 10 N
F=ma
a=F/m
a=2000/1000
a=2 m/s^2

As per Newton's law rate of change in momentum is net force
so we can write it as
now we know that
from above equation
so he will experience 900 N force in above case
Answer:
Vx= 11.0865(m/s)
Vy= 6.4008(m/s)
Explanation:
Taking into account that 1m is equal to 0.3048 ft, the takeoff speed in m / s will be:
V= 42(ft/s) × 0.3048(m/ft) = 12.8016(m/s)
The take-off angle is equal to 30 °, taking into account the Pythagorean theorem the velocity on the X axis will be:
Vx= 12.8016 (m/s) × cos(30°)= 11.0865(m/s)
And for the same theorem the speed on the Y axis will be:
Vy= 12.8016 (m/s) × sen(30°)= 6.4008(m/s)
