A bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J
Calculate the momentum of a boat with a mass of 95kg moving at 2m/Ss
Answer:
190 kg m/s
Explanation:
Momentum = Velocity × Mass
→ Substitute in values
2 × 95 = 190 kg m/s
The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.
What is Momentum?Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -
p = mv
It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.
Given is a boat with a mass of 95 Kg moving at 2 m/s.
Mass [m] = 95 Kg
Velocity [v] = 2m/s
We can write the momentum as -
p = mv
Substituting values, we get -
Momentum [p] = 95 x 2 = 190 Kg m/s
p = 190 Kg m/s
Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

In handball, who is the only player allowed in the goalie area?
Answer:
Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

A 4 kg object is moving at a speed of 5 m/sec. How much kinetic energy does the object have? A. 10 joules B. 20 joules C. 50 joules D. 100 joules
Answer:
A. 10 joules
Explanation:
Given parameters:
Mass of object = 4kg
Speed = 5m/s
Unknown:
Kinetic energy of the the object = ?
Solution:
Kinetic energy is the energy due to a moving body.
So;
mathematically;
K.E = [tex]\frac{1}{2}[/tex] x m v²
m is the mass
v is the velocity
K.E = [tex]\frac{1}{2}[/tex] x 4 x 5 = 10J
The kinetic energy of the given moving object is 50 J. The Kinetic energy of an object is the energy due to its motion.
What is Kinetic energy?The Kinetic energy of an object is the energy due to its motion. It can be given as
[tex]KE = \dfrac 12 mv^2[/tex]
Where,
[tex]m[/tex] - mass = 4 kg
[tex]v[/tex] - velocity = 5 m/sec.
Put the values in the formula,
[tex]KE = \dfrac 12 4 \times 5^2\\\\KE = 50 \rm \ J[/tex]
Therefore, the kinetic energy of the given moving object is 50 J.

If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Power = [tex]\frac{670}{60}[/tex] = 11.2Watts

Calculate the horizontal force that must be applied to a 1,300 kg vehicle to give it an acceleration of 2.6 m/s² on a level road.
500 N
3,380 N
1,302.6 N
0.002 N
The horizontal force must be applied to a vehicle of mass 1300 kg and of acceleration of 2.6 m/s² will be 3380 N. Hence, option B is correct.
What is Acceleration?The rate of change in an object's velocity concerning time is known as acceleration in mechanics. The vector quantity of accelerations. The direction of the net force that is acting on an object determines its acceleration.
Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well.
According to the question, the given values are :
Mass, m = 1300 kg
Acceleration, a = 2.6 m/s²
Force = 1300 × 2.6 m/s²
F = 3380 N.
So, the force applied will be, 3380 N.
