A brick is thrown upward from the top of a building at an angle of 20° to the horizontal and with an initial speed of 11 m/s. If the brick is in flight for 3.4 s, how tall is the building? m

You toss an apple horizontally at 8.4 m/sm/s from a height of 2.0 mm. Simultaneously, you drop a peach from the same height. How long does apple take to reach the ground? How long does peach take to reach the ground?

A brick is thrown upward from the top of a building at an angle of 15° to the horizontal and with an initial speed of 12 m/s. If the brick is in flight for 3.3 s, how tall is the building? m

Three balls are launched simultaneously, as in the figure. The red ball is launched at an initial velocity Vodirected at an angle & above the horizontal. The blue ball is launched vertically with a speed of 10.3 m/s, and the yellow ball is launched horizontally with a speed of 5.20 m/s. The blue and red balls reach identical maximum heights and return to the ground at the same time, and the red ball returns to the ground to meet the yellow ball at the same place along the horizontal. Find (a) the launch speed vo and (b) the launch angle for the red ball. hmax 10.3m/s VO A 5.20 m/s (a) Number i (b) Number i Units Units

The maximum horizontal distance a boy can throw a ball is 50 m. Assume he can throw with the same initial speed at all angles. How high does he throw the ball when he throws it straight upward?

A hot-air balloon of diameter 12 m rises vertically at a constant speed of 15 m/s . A passenger accidentally drops his camera from the railing of the basket when it is 15 m above the ground. If the balloon continues to rise at the same speed, how high is the railing when the camera hits the ground?

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.40 m/s2 . When it is 245 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). How high is the rocket when the canister hits the launch pad, assuming that the rocket does not change its acceleration?

A rock is thrown from the edge of the top of a 86 m tall building at some unknown angle above the horizontal. The rock strikes the ground a horizontal distance of 60 m from the base of the building 6 s after being thrown. Assume that the ground is level and that the side of the building is vertical. Determine the speed with which the rock was thrown.

A car is traveling horizontally at 19.3 m/s at the moment it drives off the top of a 5.19 m tall cliff. Assuming no air-resistance can be ignored, what horizontal distance does the car travel before stiking the ground?
