A truck starts from rest down a hill with a constant acceleration. It achieves 400 meters in 20 seconds. If the weight of the truck is 7 tons then what will be the force acting on it?
Correct Answer
14000 Newtons
Find Acceleration: s = ut + ½at². - 400 = 0 + 0.5 * a * (20)². - 400 = 200a => a = 2 m/s². Find Force: F = ma. - Mass = 7 tons = 7000 kg. - F =......

💡 Analysis & Explanation
Find Acceleration ▼
s = ut + ½at².
- 400 = 0 + 0.5 * a * (20)².
- 400 = 200a => a = 2 m/s².
Find Force ▼
F = ma.
- Mass = 7 tons = 7000 kg.
- F = 7000 * 2 = 14000 N.
