I am Lyosha [343]

Answer:

The acceleration and time are 588 m/s² and 0.071 sec respectively.

Explanation:

Given that,

Speed = 42.0 m/s

Distance = 1.50 m

(a). We need to calculate the acceleration

Using equation of motion

v^2=u^2+2as

a=\dfrac{v^2-u^2}{2s}

Put the value in the equation

a=\dfrac{42.0^2-0}{2\times1.50}

a=588\ m/s^2

(b). We need to calculate the time

Using equation of motion

v = u+at

t=\dfrac{v-u}{a}

t=\dfrac{42.0-0}{588}

t=0.071\ sec

Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.

A ball is dropped from the top of a building.After 2 seconds, it’s velocity is measured to be 19.6 m/s. Calculate the accelerati
zlopas [31]

Answer:

acceleration, a = 9.8 m/s²

Explanation:

'A ball is dropped from the top of a building' indicates that the initial velocity of the ball is zero.

u = 0 m/s

After 2 seconds, velocity of the ball is 19.6 m/s.

t = 2s, v = 19.6 m/s

Using

v = u + at

19.6 = 0 + 2a

a = 9.8 m/s²

ahrayia [7]

Since distance is a scalar and not a vector, the total distance traveled is the sum of all the distances covered throughout the journey.

In Physics, we have two categories of quantities;

  • Vectors
  • Scalars

The difference between vectors and scalars is that vectors has direction but scalars do not have direction. Both quantities posses magnitude.

The total distance covered can be obtained algebraically since distance is a scalar.

Hence, total distance covered = 2 cm + 6cm + 5 cm = 13 cm
