Given : An empty truck with a mass of 2500 kg has an engine that will accelerate at a rate of 1.5 m/s²
To Find : What will be the acceleration when the truck has an additional load of 1500 kg
Solution:
Force = mass * acceleration
Empty truck Mass = 2500 kg
acceleration = 1.5 m/s²
Force = 2500 * 1.5
=> Force = 3750 N
additional load of 1500 kg
=> Total Mass = 2500 + 1500 = 4000 kg
3750 = 4000 x a
=> a = 3750 /4000
=> a = 0.9375 m/s²
acceleration when the truck has an additional load of 1500 kg is 0.9375 m/s²
