A 1000 kgkg car pushes a 2000 kgkg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of
the car push against the ground with a force of 4500 NN.
1 answer:
Answer:
Explanation:
A car of mass 1000kg pushes 2000kg
The forward force is 4500N
Then, summation of the forward forces is ma
ΣF = Σ(ma) = m1a1 + m2a2
Since the body are moving together then, they will have the same acceleration(a)
ΣF = Σ(ma) = (m1+m2)a
Let m1=1000kg.
m2=2000kg
F=4500N
Then,
4500=(1000+2000)a
4500=3000a
Then,
a=4500/3000
a=1.5m/s²
