Pendulum mass is 4 kg. Use your equations for gravitational potential energy and kinetic energy to determine these values based
on the data given below. Total energy is the sum of gravitational potential energy and kinetic energy. In this problem, round gravity to: g = 10 m/s2.

Explanation:
Total mass=mass of skate board + mass of rider
Total mass(m)=46kg + 4kg
Total mass(m)=50kg
Acceleration(a)=3m/s^2
Force(f)=mass x acceleration
Force=50 x 3
Force=150N
