An object traveling 200 feet per second slows to 50 feet per second in 5 seconds. Calculate the acceleration of the object. Use the following formula: Variable
Equation
Solve

-30m/s²

Explanation:

acceleration = change in velocity ÷ time

change in velocity = final velocity - initial velocity = 50 - 200 = -150m/s

time = 5s

Substitute in the values:

acceleration = -150 ÷ 5 = -30m/s²

The value is negative because the object is decelerating, slowing down

the answer is b i think

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
