Answer:
x=22.33m
Explanation:
Kinematics equation for constant deceleration:

Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
Answer:
200 N = 200 Newtons
Explanation:
Just use the formula F = m*a
F = Force in Newtons
m = mass and is 20 kg
a = acceleration and is 10 m/s^2
F = 20 * 10
F = 200 Newtons.
