Answer: The squishy ball
Explanation:
The squishy ball experiences a larger force due to its soft nature. The force of the squishy ball cannot overcome the concrete cube due to the weight of the concrete and as such the weight of the concrete cube will overcome the force exerted on it by the squishy ball making the ball to experience much larger force.
c. Energy and work
Explanation:
Energy and work done have the same unit of measurement. The unit of energy and work done is taken as the Joules(J).
- Energy is defined as the ability to do work. Energy is of two main forms.
- Potential energy is the energy at rest while kinetic energy is due to the motion of a body.
- All forms of quantitative energy calculations are expressed as the joules.
- Work done is the force applied to move a body through a particular distance.

Answer:
2666 kg
0.11567 m/s²
Explanation:
m = Mass of boat
a = Acceleration of boat
From Newton's second law
Force
Force on the first boat is 333.25 N
Hence, mass of the second boat is 2666 kg
Combined mass = 2666+215 = 2881 kg
The acceleration on the combined mass is 0.11567 m/s²
