Im pretty sure that it applys
Answer:
Acceleration = Final velocity-initial velocity/time
In m/s^2
a = 40000-0 /10
= 4000m/s
in km/h
a = 40/10÷360
= 1440km/h
The amount of force required to accelerate the given mass of the wagon is 129 Newtons.
<h3>What is force?</h3>
A force is simply referred to as either a push or pull of an object resulting from the object's interaction with another object.
From Newton's Second Law, force is expressed as;
F = m × a
Where is mass of object and a is the acceleration.
Given the data in the question;
- Mass of the rock m = 8.6kg
F = 8.6kg × 15m/s²
F = 129kgm/s²
F = 129N
Therefore the amount of force required to accelerate the given mass of the wagon is 129 Newtons.

K.E= 50,000 Joules= 1/2mv^2=1/2x1,000kgxv^2
v^2=2x50,000 Joules/1,000kg = 100m^2/v62
v=10m/s
The speed of the car is 10 m/s
Formula for time: velocity/distance **Going to use GRESA
Given: v=65mi/hr d=115mi --- Required: time=? --- Equation: v/d --- Solution: 65mi/hr / 115mi = 0.57 hr --- Answer: 0.57 hr
