According to John daltons observations, when elements combine in a compound

How much time does it take to travel from the position of 25m to a position of 100m at an average speed of 15m/s?

A race car starts from rest and travels east along a straight and level track. For the first 5.0 s of the car's motion, the eastward component of the car's velocity is given by vx (t) = (0.890m/s3) t2.

a bus is moving with a constant velocity 10m/s along horizontal rode. a man standing inside bus throws ball virtically upward with valocity 8 m/sec WRT tohimself and cathes the ball. the magnitude of displacment of ball WTR ground will be
