Answer 1

There are three types of sadistic questions often used to test your understanding of work. ... A 70 kg cart is pushed for 50 m with a constant velocity upon a 45º frictionless incline.

Answer 2

$300 - 150 \div t \times 8 = 400$
f=ma , 3
$a = v - u \div t$
m= 8
$400 \div 8 = 50$
$300 - 150 \div 50 = 3$
3s = t
