Question

Use gravitational force as 10n,weight is measured in n and mass is measured in kg.acceleration at 30ms negative square 1000kg=1 ton 1000mg=1kg
1.a loaded truck weighing 35 tonnes was accelerating at 30ms negative square and hit a stable rock. Calculate the force on the rock.

Answer 1

Answer on Question #58164-Physics-Mechanics-Relativity

Use gravitational force as 10n, weight is measured in n and mass is measured in kg. Acceleration at 30ms negative square 1000kg=1 ton 1000mg=1kg

1. A loaded truck weighing 35 tonnes was accelerating at 30ms negative square and hit a stable rock. Calculate the force on the rock.

Solution

The force on the rock is given by the Second Newton's law:

$$F = m a = 3 5 \cdot 1 0 0 0 \mathrm {k g} \cdot 3 0 \frac {m}{s ^ {2}} = 1 0 5 0 0 0 0 N = 1 0 5 0 k N.$$

Answer: 1050000 N = 1050 kN.
