A 12 g plastic ball is dropped from a height of 2.5 m and is moving at 3.2 m/s just before it hits the floor. How much mechanica

Nataly [62]

Answer:

0.24

Explanation:

Mass of ball= 12g=0.012Kg

height of ball= 2.5m

velocity of ball before falling= 3.2m/s

potential energy of the ball=mgh= 0.012*10*2.5=0.3J

kinetic energy of the ball=0.5*m $v^{2}$ =0.5*0.012*3.2*3.2=0.6J

Loss in mechanical energy during the fall= potential energy- Kinetic energy= 0.3-0.06=0.24J

note: During the fall, the potential energy of the ball is converted to kinetic energy. the loss in energy is due to air resistance.

A plane accelerates down a runway. The plane accelerates at 2 m/s/s for 10 seconds and obtains a speed of 20 m/s. What speed wou

otez555 [7]

here acceleration initially is given as 2 m/s/s for total time of 10 s

so in above situation the final speed will be 20 m/s

now here if acceleration is double as well as the time is also double

so now we will have

$a = 4 m/s^2$

$t = 20 s$

so now the final speed is given as

$v_f = 4 (20)$

$v_f = 80 m/s$
