A4 g bullet is fired horizontally with a speed of 300m/s into 0.8 kg block of wood at rest on a table. if the coefficient of friction between block and table is 0.3, how far will the block slide approximately?

d = 3784.5 m

Explanation:

First bullet goes into the block and fixed into it

so here the speed of the combined is given by momentum conservation

so it is given as

here we know that

now from above formula

now the coefficient of friction on the floor is given as

so the deceleration is given as

now from equation of kinematics we know that

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
