Question

5.) A 10 Newton force and a 25 Newton force act concurrently on an object. magnitudes of the What are the biggest and smallest possible resultant forces form those forces? 6.) A 10 Newton force is applied to a 5-ke block at an angle of 30 above the horizontal. The block slides across the frictionless, horizontal surface. a. What is the acceleration of the block? b. What is the normal force acting on the block from the surface? vn 7J A 10-kg block is released from rest at the top of a frictionless incline with an angle of inclination of 30. What is the acceleration of the block as it slides down the ramp? 8.) A 1-kg cart is sliding along a frictionless horizontal surface with a speed of 3 m/s when it collides with a stationary cart that has a mass of 2 kg. The carts stick together after the collision. How fast are the carts the collision? 9.) A1-kg ball is thrown with a velocity of 40 m/s east. A player hits the ball with a bat, and exerts an impulse of 70 kg m/s west on the ball over a period of 0.001 seconds. What is the velocity of the ball after it was hit? a. b. What is the magnitude of the average force the bat exerts on the ball over this time interval?

Explanation / Answer

Ans 5 :

The force is a vector quantity.

So when the direction is same of the forces on the object , the values get additive and when the directions are opposite , the values get subtractive.

So here the biggest possible resultant force will be : 10 + 25 = 35 N

and the smallest possible resultant force will be : 25 - 10 = 15 N
