Question

Grrr i don't have much time, help please T^T

Answer 1

Answer:

2. ( b ) zero

3. ( c ) 10 s

4. Uniform then decreasing

Explanation:

2.

Since the motion is uniform, initial and final velocity will be 0, hence acceleration will be zero.

3.

Initial velocity ( u ) = 5 m/s

Final velocity ( v ) = 35 m/s

Acceleration ( a ) 3 m/s^2

To find : Time ( t )

Formula : -

t = v - u / a

 = 35 - 5 / 3

 = 30 / 3

t = 10 s

Answer 2

Answer:

See below ~

Explanation:

Q2

The uniform circular motion in the movement of object in a circular path with fixed and perpendicular on the direction of the motion acceleration.

• d

Q3

• Substitute the values in : v = u + at
• 35 = 5 + 3t
• 3t = 30
• t = 10s (c)

Q4

The vertical component for a projectile by acute angle on the horizontal axis changes from decreasing then increasing velocity.

• d
