if a force is applied to an object is not greater than the starting friction what will happen to the object

1 answer:

4 0

If you match the amount of static friction that can be generated when the object is at rest, it will not move because there is zero force the force has to be greater that the static friction in order to have it include motion. But if there was any more force will cause acceleration otherwise if it was lower force it will deceleration.

A golf ball with an initial angle of 34° lands exactly 240 m down the range on a level course.

g100num [7]

Answer:50.39 m/s,

40.46 m

Explanation:

Given

launch angle $=34^{\circ}$

Range=240 m

We know that Range $=\frac{u^2sin2\theta }{g}$

$240=\frac{u^2sin(68)}{9.81}$

u=50.39 m/s

(b)maximum height of projectile is given by

$H=\frac{u^2sin^2\theta }{2g}$

$H=\frac{50.39^2(sin34)^2}{2\times 9.81}$

H=40.46 m

A block is sent up a frictionless ramp along which an x axis extends upward. The figure below gives the kinetic energy of the bl

ss7ja [257]

Kinetic energy =1/2 mv^2

m=2ke/v^2 

m=2(34)/3.6^2 

m=5.24 

force normal = mg 
=5.24 x 9.8 
force normal = 51.4N
