PLS HELP ASAP I WILL GIVE BRAINLIEST PLSSS :) 4. When solving projectile motion problems where the projectile is launched at an angle, the first step is to find the x- and y-component of the initial velocity. Why is this helpful in solving these types of problems?

5. Candace throws a ball so that it has a horizontal velocity of 6.2 m/s, and vertical velocity
of 2.1 m/s. What is the velocity vector of this ball right as she releases it?

Question 4:

» Acceleration due to gravity.

• When solving projectile motion. For vertical motion, acceleration due to gravity is included whereas in horizontal motion, acceleration due to gravity is excluded.

Question 5:

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
