A block with a mass M = 4.85 kg is resting on a slide that has a curved surface. There is no friction. The speed of the block af
natali 33 [55]

Answer:

The correct option is a

Explanation:

From the question we are told that

   The mass of the block is  m =  4.84 \ kg

    The height of the vertical  drop is h =  19.6 \  m

Generally from the law of energy conservation , the potential energy at the top  of the slide is equal to the kinetic energy at the point after sliding this can be mathematically represented as

        PE  =  KE

i.e     m *  g  *   h   =  \frac{1}{2} *  m *  v^2

=>    gh  =  0.5 v^2

=>   v = \sqrt{\frac{9.8 *  19.6}{0.5 } }

=>    v = 19.6 \  m/s

What are the signs of the velocity, force, and acceleration (components) afterthe cart is released and is moving qway from the m
SVETLANKA909090 [29]

Answer:

car is moving away its direction is negative.

the speed must also be negative.

speed this distance decreases the acceleration is negative and if the speed is increasing the acceleration is positive.

Explanation:

In the exercise they indicate that the direction to the motion sensor is positive, as they indicate that the car is moving away its direction is negative.

The speed of the car is

           v = (x₂-x₁) / t

As the positions are negative, and the car moves away the speed must also be negative.

The analysis for acceleration must be very careful if the speed this distance decreases the acceleration is negative and if the speed is increasing the acceleration is positive.
