Speed is the magnitude of the velocity. When we say speed is constant, we mean that the magnitude of the velocity is constant. If the speed of a particle is constant can we say that it doesn't experience any acceleration?
A firework is projected from the level ground in such a way that v0y = 10m/s and v0x = 20 m/s.a) Find the time it takes the firework to reach its maximum height reached.b) Since the firework returns to the ground, it has the same initial and final height. Whenthis happens, the time it takes the object to land is twice the time it takes to reach its maximum height. Using this information, find the horizontal and vertical components of the velocity of the firework right as it lands.
A steel ball is dropped onto a hard floor from a height of 1.75 m and rebounds to a height of 1.25 m. Use a coordinate system in which the vertical component of velocity is positive in the upwards direction. Calculate its velocity, in meters per second, just before it strikes the floor. Calculate its average acceleration, in meters per second squared, during its contact with the floor if that contact lasts 0.0800 ms (8.00 × 10-5 s).
