two projectiles are fired at equal speeds but differentangles. one is fired at an angle of 30 degrees and the other at 60degrees
zheka24 [161]

Answer:

a) 30 degree

Explanation:

As we know that time of flight of the projectile depends on the the vertical component of the velocity always

It is given as

T = \frac{2v_y}{g}

now we know that

v_y = vsin\theta

so we will have

T = \frac{2vsin\theta}{g}

since we know that two projectiles are projected at same speed but different angles

so smaller the angle will take smaller time

so it would be 30 degree projectile which will take smaller time

An 8 Newton wooden block slides across a horizontal wooden floor at constant velocity. What is the magi notice of the force of k
kondaur [170]

Answer:

The force of kinetic friction between the block and the floor is 2.4 N

Explanation:

The given parameters are;

The weight of the block = 8 Newtons

The velocity of the block = Constant velocity

Taking the kinetic friction for wood, \mu _k = 0.3, we have;

The normal reaction of the block on horizontal ground, N = The weight of the block = 8 N

The force of kinetic friction between , F_k = \mu _k × N

Therefore, we have;

The force of kinetic friction between the block and the floor, F_k = 0.3 × 8 N = 2.4 N.
