Question

An 850 kg car is moving to the right at a constant speed of 1.44m/s. What is the acceleration?

a)Constant speed means ZERO acceleration.
b) 1.44 m/s²
c) 9.8 m/s²
d) 1850 m/s²

Answer 1

The acceleration of the car is zero since it is moving at a constant speed. where a is the acceleration, v is the change in velocity, and t is the time taken. Since the car is moving at a constant speed, there is no change in velocity, so the acceleration is zero (option a).

Step-by-step explanation:

The acceleration of the car can be determined using the formula a = v/t, where a is the acceleration, v is the change in velocity, and t is the time taken. Since the car is moving at a constant speed, there is no change in velocity, so the acceleration is zero (option a).

acceleration of the car is zero since it is moving at a constant speed. where a is the acceleration, v is the change in velocity, and t is the time taken. Since the car is moving at a constant speed, there is no change in velocity, so the acceleration is zero (option a).
