A bus is moving forward at 20 m/s. A student on the bus throws a tenis ball horizontally at
seraphim [82]

Answer:

D: 35 m/s

Explanation:

The bus is moving at a speed of 20 m/s.

Thus; v_bus = 20 m/s

Tennis ball thrown horizontally towards the front of the bus is given as 15 m/s.. Thus, v_ball = 15 m/s

No, due to the fact that the bus and the ball are moving at the same time, an observer will think the speed is the sum of that of the ball and the bus.

Thus, it will appear to an observer on the sidewalk that the speed is; v_bus + v_ball = 20 + 15 = 35 m/s

1. You apply a force of 67.0 N to a mass of 1.43 kg. What is the acceleration of the object?
telo118 [61]

46.58m/s²

26.43kg

Explanation:

Given parameters:

Force = 67N                           force = 185N

Mass = 1.43kg                         acceleration = 7m/s²

Unknown:

Acceleration = ?

mass of the object = ?

Solution:

According to newton's second law of motion "the net force on a body is a product of its mass and acceleration".

   Force = mass x acceleration;

For the first problem;

the unknown is the acceleration;

   Acceleration = \frac{force }{mass} = \frac{67}{1.43} = 46.58m/s²

Using the same law, to find the mass of the second object, we make it the subject of the formula;

     mass = \frac{force }{acceleration}

   mass = \frac{185}{7} = 26.43kg
