A loaded grocery cart is rolling across a parking lot in a strongwind. You apply a constant force vector {F} =( 28 N )\hat{i} - ( 43N )\hat{j} to the cart as it undergoes a displacement vector {s} =(- 9.5 m )\hat{i} - ( 3.7 m )\hat{j}.

How much work does the force you apply do on the grocery cart?

hi,

i have 5 questions i need the complete solutions with theirfinalresults. is there anyone could help me, i wouldappreciatethat.

1)A worker pushes a sled with a force of 40 N over
a level distance of 6.0 m. If a frictional force of 24 N actsonthe
wheelbarrow in a direction opposite to that of the worker, whatnetwork is
done on the wheelbarrow?

2)
A horizontal force of 200 N is applied to a
55-kg cart across a 10-m level surface. If the cart acceleratesat2.0 m/s2,
then what is the work done by the force of friction as it actstoretard the
motion of the cart?

3)
If both mass and velocity of a ball are tripled,
the kinetic energy is increased by a factor of:

a) 9, b) 12, c) 3, d) 6

4)
A 1 200-kg automobile moving at 25 m/s has the
brakes applied with a deceleration of 8.0 m/s2. How far does thecartravel
before it stops?

5)
Samantha pushes a 50-N crate up a ramp 25.0 m in
length and inclined at 10Â° with the horizontal. Whatpotentialenergy
change does the crate experience?

thank you in advance

A floating ice block is pushed through a displacement vector d= (15 m)i - (12 m)j along a straight embankment by rushing water,which exerts a force vector F = (210 N)i - (150 N)j on the block.How much work does the force do on the block during the displacement?
