Numerade educator with a knack for mathematical storytelling. I make algebraic narratives and calculus adventures engaging, unlocking the narrative behind the numbers for a captivating learning experience.
A car travels at 54 km/h for first 20 s, 36 km/h for next 30 s and finally 18 km/h for next 10 s. Find its average speed.
"A train accelerates from 36 km/h to 54 km/h in 10 sec.(i) Acceleration(ii) The distance travelled by car."
A truck travelling at 54 km/h is slow down to 36 km/h in 10 sec. Find the retardation
A scooter travelling at 10 m/s speed up to 20 m/s in 4 sec. Find the acceleration of scooter.
A train starts from rest and accelerate uniformly at the rate of 5 m/s2 for 5 sec. Calculate the velocity of train in 5 sec.
"A object moves with uniform positive acceleration. Its velocity-time graph will be(a) A straight line parallel to the time axis(b) A straight line inclined at an obtuse angle to the time axis(c) A straight line inclined at an acute angle to the time axis(d) None of these."
