Answer:
12.76 m.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 11.9 m/s
Angle of projection (θ) = 59°
Acceleration due to gravity (g) = 9.8 m/s²
Horizontal distance (i.e Range) (R) =?
The horizontal distance other wise known as range from the base of the building to which the rock will strike the ground can be obtained as follow:
R = u²Sine2θ / g
R = 11.9² × Sine (2×59) / 9.8
R = 141.61 × Sine 118 / 9.8
R = 12.76 m
Therefore, the horizontal distance from the base of the building to which the rock will strike the ground is 12.76 m

Answer:
Normal force of 10,000N
Explanation:
From the question, the weight the car exerts on the pavement is 10,000N.
The pavement exerts upward and perpendicular contact force called normal force on the car to support its weight. Also, the normal force is equal and opposite to the weigh of the car.
Hence the pavement exerts normal force of 10,000N back on the car to prevent it from passing through it.
Answer:
Explanation:
The speed of the actor before the collision is found by means of the Principle of Energy Conservation:
The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:
Lastly, the maximum height is determined by using the Principle of Energy Conservation again:
