An object is projected horizontal at 10 m/s from the top of a tower 20 m high. Calculate the horizontal distance travelled by the particle when it hits the level ground. [g = 10 m/s2]

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

The mini-refrigerator fire was most likely caused by what type of wiring?
