JEE Main 2022 Physics question
At time t = 0 a particle starts travelling from a height 7ẑ cm in a plane keeping z coordinate constant. At any instant of time it's position along the and ŷ directions are defined as 3t and respectively. At t = 1 s acceleration of the particle will be
Answer: (2)
Solution
x = 3t gives = 0, and gives = . At t = 1 s the acceleration is 30 ŷ.
