How much work is done by a person who picks up a 3-kg crate from the floor, raises it 2m and sends it flying with a speed of 4m/
erastovalidia [21]

Answer:

  82.8 J

Explanation:

The work done to raise the crate is ...

  PE = Mgh = (3 kg)(9.8 m/s^2)(2 m) = 58.8 J

The kinetic energy added to send the box flying is ...

  KE = (1/2)Mv^2 = (1/2)(3 kg)(4 m/s)^2 = 24 J

So, the total work involved in this activity is ...

  58.8 J +24 J = 82.8 J

What is the acceleration of the object?<br>______ m/s2​
professor190 [17]

Answer:

Explanation:

this graph show the decrease in velocity  with time

at time t=0 velocity is 40 m/sec

at time t=12sec velocity is decreases from 40 to 10 m/s

so the acceleration of the object at time=12 sec is

a=v/t

a=Δv/t

Δv=v1-v2=40-10=30 m/s

a=30/12=2.5 m/s^2
